This really isn't a true head-to-head showdown. I've just spent a lot of time using the RMD and I'm very comfortable
working with it. It has been the current "knife" for a long time so it makes a good "bar".

I've spent almost two weeks using the 5.1 and I've spent a lot of quality time with it. Everything from starting to recreate a
project shelter to whittling to fondling it while I watch TV.

Is the RMD still the "current" knife or has it been replaced?

First impression upon unboxing: Cheezuz Crust! This knife is FINE! It is extremely well made. Perfect grind, sharp(!), excellent finish.
The workmanship during the manufacturing puts the 5.1 among the finest knives I've had in my hands (I've held a few Winkler II's
and those were pretty amazing. Not sure if they were any better though).

I did have a frowny face moment that made me doubt. The RMD handle is about the perfect size for my hands and makes it a joy
to work with. It just fits. The 5.1 handle is much thicker and didn't feel natural. My hand didn't feel like it was "one" with the
knife. And in my opinion/experience, that is not good. It can lead to fatigue and accidents. It makes a knife no fun to use.

I've waffled on choils. It really depends on the knife. The RMD choil is decent. I can choke up just fine. The 5.1 choil does not work well for me.
It's too small (I wear large or medium gloves depending on brand). Photos are from first sit-down-and-whittle session trying to get a
feel for the 5.1. Choked up and squeezed a little, jimping could be a hot spot generator. Already got a red streak jus below the thumb.
Not sure if you can see it...

Did I mention sharp? Did not even feel this. Out come the gloves.

I won't show it all but I spent 5 or 6 days (a lot of hours) whittling, processing firewood, etc. Nothing big but lots of repetition
testing the edge retention with push cutting and slicing, shaving curls, batoning with and against the grain. My wife even let me sit
at the kitchen table and carve, taking feather sticks down to nothing but a paper plate of shavings and curls. Taking this:

Shaping inside and outside radius. RMD had a bit of an advantage here on inside radius.
The tip just fit a little better:

Edge retention was impressive. At most, I stropped the edge every other night. Maybe 5-7 swipes for each side. It probably wasn't
necessary, though.

Next step is to take it out and do some heavier tasks. Didn't get to spend too long. Forgot bug spray. This shelter was built with
a hatchet and a Rodent 7 and TGLB. It needs to be relocated. Plus, I have a few techniques for joining/joints I want to try. The
only tools I'll be using is an axe, a folding saw and the 5.1. It will be on ongoing project for a couple weeks.
I'll post progress photos it people are interested.

Rebuilding here:

Using the saw to cut to length and cut guide lines for depth and width for notches. The 5.1 does all the clean up and finer work.
Side note: I learned that saws do NOT cut with the grain very well. At all. It just seemed to churn up fibers and push them back
and forth. Interesting...

First post attempt:

Something I have not done with the RMD much as much. The shape/thickness of the tip just doesn't work as well. I used
the 5.1 almost like a chisel. I could lay the blade flat and tap it through the notch. It shaved off thin (or thick) layers pretty
consistently. I was expecting the tip to pop out or rise as it moved but it didn't. Pretty cool for doing notches!

Gotta get better with the saw! Slanted notch like that will, I think, let me build a free standing frame without cordage. The cross
beam has a matching wedge that fits in snugly. The slope doesn't allow the beam to roll out, and gravity plus the weight of any
additional beams will help hold it in place even more. That's the theory, at least. We'll see!

Second post attempt, a little better. Learning as we go!!

The work in the woods involved some controlled batoning, carving, using the tip as a chisel, twisting the tip and edge to "pop" out the
strips defined by the saw cuts. How did the 5.1 do?

It's dirty! GASP!!!!

Well, mixed results, really.

The GOOD:
- The time I spent with it was worth it. I think my initial thoughts on the handle were due to familiarity. I was used to the
RMD so it felt great. I now feel that way about the 5.1. Yes, a person can get used to pretty much anything given enough time and
determination (read: forcing it). I do not feel like this is a forced comfort. The 5.1 grew on me and I feel like I can use it as well
and, in some tasks, better than the RMD. The RMD still seems to get into tight spaces a little better, like cleaning up tiny notches
for traps?

- It's a really good size! I really like the blade length and, surprisingly, the width! It felt really nimble easy to control. I thought
for this kind of work the RMD would have a bit of an edge (PUN!) due to it's slightly smaller size. BUT this is almost a tie with the
RMD. I might give the nod to the 5.1 eventually. It was that nice to work with.

- The 5.1 seems to be able to do fine work. I was able to push cut a few notches really close together in some pretty brittle wood
with the 5.1 due to the blade geometry. The RMD tended to split the wood easier.

- The edge stayed sharp! I was able to shave out thin layers and do some pretty fine adjusting without any issues.


The BAD:
- This kind of contradicts the last point above (about staying sharp). The edge did disappoint a bit. When I got home and washed the dirt off
I did a full inspection. I used some of the convenient larger curls from whittling (still on the paper plate on the kitchen table) to test
the edge. Slowly dragging the wood down the length of the blade revealed several small chips or dings. They were small enough that I couldn't
really see them with the naked eye and I could barely make them out using a magnifying glass. But the curls and paper would "catch" here and
there along the blade. The edge was very easy to "repair" using ceramic rods and leather (using a Work Sharp Field Sharpener since that's what
I'd have in the field). It took maybe 3 to 4 minutes. So is it that big of a deal? Probably not. But Dang! I was hoping that the 3V would stand
up a little better. I didn't feel like I was using the knife all that hard or long enough for this to occur. I did not use the RMD on this trip
but I've used it in the past and my sense is the the SR-101 in the RMD might hold up a bit better. But I can't say for sure.

So that's where I am. Do I like the 5.1 Hellz, yeah!!!! Am I happy with it? Hellz, yeah!! Well, done Guy and company!!

I am going to keep using it to rebuild that structure and see how it holds up. The edge thing gives me a little pause but the jury is still out on that.
If what I experienced is the worst that happened with this kind of use and how easy it was to remedy, it will probably be a non-issue in my opinion.
The RMD will be a backup for a bit so the 5.1 can get full broken in.

I am excited to get back out there and see how it goes. I'm going to try to get out there at least 3 times a week so I'll add to this thread as
I progress.

I can't wait to include the 4.7, 6 and 7/7 I've got on order into the trials. I might have to throw in a 10.

Take care!

Great write up and pics- thanks for taking the time to share. :thumbup:
 
What a fantastic bunch of pictures and explanation of what you're doing with the knife. That's some pretty impressive work on that shelter too! Silky saws are amazing, I wonder if one with finer teeth would do better with the ripping cuts?

Looking forward to updates on your shelter.
 
Awesome work. Thanks for writing it all down for us.

I have a 5, and specifically like it because it has no choil.
I too found the blade geometry of the blade to work well, and overcome the thickness of the blade. I was worried it would split things rather than cut them.

I still think I'm going to get a 4.5 to try, just because I like thin blades.

We are interested! Thanks for all the pics and the write-up.

A strange phenomenon with the new 5.1, when you look at this picture, the size difference in comparison to the RMD is apparent......

IVyKtIC.jpg


.......but the 5.1 does not feel as much bigger as it looks. I think that is a tribute to it's design that it feels so nimble.

On the topic of saw blades, any alternating bevel tooth is designed for cutting cross-grain, and your gomboy looks ideal for that. A rip blade will have a much straighter tooth geometry, and many fewer teeth. Think of how you are shaving feather sticks. You are essentially taking one 'tooth' and making a rip cut in the same direction as the grain, a 'stringy' cut. An FTG (flat-top ground) tooth on a saw blade acts in a similar manner, and fewer teeth perform much better for such a cut, provided the geometry is correct. The ATB (alternate-top bevel) tooth on the gomboy is not going to allow the tooth/gullet configuration to clear the stringy chips that are produced in a ripping-type cut, thus the rubbing of material you were experiencing.

Probably too much information, sorry if so, but saw blades are what I deal with every day. Usually power vs hand, though, but some things are universal.

Looking forward to your next write-up. Thanks again.
 
That was a great explanation of saws and tooth patterns. I hadn't really thought about it but your information makes sense! Thanks, HK!!!
 
Great write up!!! I get excited any time I see "pic heavy" in the title. You have seen serious word working talent from loads of experience, very inspiring! So cool to see your knife getting used so well :thumbup:
Love hearing the feed back on all aspects of the knife. I'm really anxious to try my 4.7 I have on order so I can see if the new handle works for me. Hopefully your 5.1 keeps growing on you!
 
I think any edge issues you saw are a result of such a super thin geometry. For what you did, I don't feel that there was any unexpected result. The 3V allows such thin edges. Try what you did with a 1095 edge that thin and youde wreck the edge.

Overall excellent review
 
This is awesome! We love seeing the knives getting used, and it is especially neat to see it building something. Bonus because I've always been interested pre-power tool construction methods.

There is the one thing in your review that I'm hoping you all can help me out with.

I've waffled on choils. It really depends on the knife. The RMD choil is decent. I can choke up just fine. The 5.1 choil does not work well for me.

feel for the 5.1. Choked up and squeezed a little, jimping could be a hot spot generator. Already got a red streak jus below the thumb.
Not sure if you can see it...

I don't know much about any knives beyond the SURVIVE! line-up, so I'm just looking at the pictures. It appears that the choils are about the same size, if anything the GSO-5.1 choil looks like it may be slightly larger. Is it just the photos playing tricks on my eyes? What is the actual size difference there?

The jimping hot spot is...a conundrum. People want a sharpened spine, but a sharper spine means the spine is sharp. :eek: With our finish we tried to find a middle point where the spine can still work with a ferro rod, but isn't going to carve up hands.

I am definitely interested to see how the project progresses, as well as see updates about how the GSO-5.1 is working out for you. I will be looking forward to seeing which of the knives you end up preferring between the different models you have on order.

Thanks for the thorough review!
 
Riz, good comment about the thin edge. This is my first 3V knife and I wasn't really sure what to expect. I used the word "disappoint" in regards to the edge and perhaps that was a bit strong. With how easy it was to fix and how small the edge deformities were (couldn't see them unless using magnifying glass and even then it was hard) I'm not all that concerned.

Ellie, the jimping comment is an observation and not really a complaint. If I am using a knife for any length of time I usually wear gloves. The entire time I was out in the woods I did have gloves and it was a non-issue. And having that instead of a ramp for the thumb feels better.

Good question on the choil. The size is close but the RMD is a hair longer? Or maybe is isn't as much of a "circle"? In any case, it is just enough to allow my finger to get in there without hitting on the start of the edge. Your question did get me thinking so I picked up both knives and played with them a bit. One thing I think makes a big difference is hand positioning when holding. The RMD has that ramp on the back while the 5.1 is flat. The ramp can be a bit uncomfortable so I rock my palm back towards the pommel a little. This shifts my grip a bit so when I squeeze, my finger is pulling back towards the handle (like a trigger) and away from the edge. Weird. I didn't really notice it before.

It's not really a complaint. Once again, gloves to the rescue! Plus, I have used an alternate grip on knives without choils when choking up. It's sort of a pinch thing rather than a fist thing. It works just as well.

In any case, I am more that happy with the 5.1.

After reading this, and checking out your pics, I think it's time to redo my little camp. I get tired of pulling it apart every spring and using new lashings in different locations so as not to harm the living trees. I believe I need to build it more like your camp. Everything notched and supported with no lashings. I'm really interested in following your progress. I hope you don't mind me stealing some of your ideas.

Steal away! I'm heading back out this afternoon. The first couple of attempts identified some areas for improvement. I'm excited to try them out. I was thinking of putting together a hammock stand, too. For those times when trees don't want to cooperate!

The Outdoors are awesome.

No worries, I just wanted to address the jimping in case anyone reading might wonder why it is like that. Guy puts a lot of thought in every detail so there is usually a why or why not for anything that comes up.

Very interesting about the different holds. I definitely see what you are talking about in regards to the extra hump being in the way for that same grip. Thanks for taking the extra time and the pictures! As I said, I really don't know much about other knives so there is always room to learn something new when comparisons like this come up. I doubt I'll ever be in the market for a non-SURVIVE! knife, but at least I might be better prepared to answer a customer question or keep up with another bf conversation now.

I think you hit the nail on the head regarding the choils. When I got my new 5.1 I was really surprised that the choil did not work for me. The choil on the previous model 5.1 worked for me. The choil on the RMD works for me, so what the heck? Like you show in your pictures, there's not much size difference in the choil itself. I hadn't really been able to get it in my head, but now that you point out the difference in grip due to handle contour, I believe you have it.

I'm glad you found the saw blade info useful. Thanks again for a great review.
 
Nice write up and pix. I don't really have any issues with the choil on my 5.1. I have XL lands but not fleshy hands and I find the handle very comfortable. Working in the trades for 20+ years my hands take a beating so the sharp edges splines and jumping are irrelevant to me. Edge retention is key for me. I've learned to deal poor ergonomics on hand tools and when I find one that is ergonomic for me I tend to hold on to them. The S!K I have will be staying with me.
