S!K 4.7 Sample Blade Reviews

I was just saying in some thread today that I did not realize how similar they were. Everyone knows my infatuation with my 5 so of course I'm drawn to the 4.7. But with how similar the new and improved 4.1 is, it has a slightly longer handle than the 4.7 and only a 1/4 inch shorter blade PLUS with a thinner blade it could cut just that much better. I'm so glad it's coming up right after the 2.7!
 
So, I spent some time doing a short cutting test yesterday. First, though, a little more about myself.

I'm a pretty average guy when it comes to gear and putting it to use. I love the outdoors, hunting, fishing, and so on, but have very little time (young family, full time carreer), and am by no means a bushcrafter, outdoorsman. I like my gear and when I buy something, I prefer to buy high quality, without getting into the very upper end of things. I shoot a Dan Wesson 1911, for example. Very high quality, darn good price. To me, Survive! falls in that category. I hate, HATE! abusing anything. I tend to take care of my stuff because I really don't like breaking things. Maybe I tend toward babying things, so putting this knife to any sort of abuse just isn't in me.

The test consisted of a piece of 3/4" thick red oak. I spent some time cutting into one end, making shavings and chips. I also did a little bit of chopping in the middle of the board. This to me represents what would happen if you hit a knot in a typical stick or piece of wood. I tried to keep the cuts in the first 1/3 of the blade nearest the handle. I took 'hacking slice' kind of strokes, push cuts, and the blade definitely cut smoothly until it hit a thicker chunk left over from the previous cut. I also tried to twist the blade a little sideways out of the chops (poor technique, on purpose), just to side load the edge a little.

The edge started out shaving sharp. It still is. There might be the slightest hint of a few rolled spots, I can only see them with my camera zoomed in, not with the naked eye. I expected the edge to take on a little more damage than that. I also expected the coating to suffer a little damage at the edge that meets up to the sharpened microbevel. I cannot discern any flakes or chips to the coating. Probably my only comment would be to the condition of the coating. It is pretty scuffed/rubbed where I did the cutting. I used WD40, Hoppes solvent, scotch brite and even a "magic eraser" to try and polish it out. I would say the marks came out about 75%, but they are still there at the right angle. They are permanent. This is by no means commenting that this is not a high quality coating, just that my preference is for uncoated blades. You would see marks on bare steel, I'm sure, but that's just my preference.

So, being the general use sort of user, I am perfectly happy with this blade. I cannot compare this to another blade, or say if it is better or worse. I think the knife held up great! I would never treat a blade like this in the field on purpose. Even in the field, I tend to go easy on my gear. This was harder use than I would put it to, so I think it did great.

Now the pictures.



Before, and After pictures of the coating. Before is just how it was after cutting (not how it came out of the box!), After is after I tried to clean it.




I tried to get pictures before and after of the edge.

The edge out of the box was, as you can imagine, perfect. After cutting, there are the slightest marks along the edge, but I cannot discern any burrs or chips when dragging my thumbnail along the edge. It still pops hairs off my arm, which is good enough for me. Here is an after picture of the edge. This is zoomed in a ways, and shows more than you can actually see with the eye.




Any questions or comments, please fire away. If you've read this far, thanks!

Awesome review, and you might be the first to post user data on the mystery knife! Double cool
 
Thanks for taking the time to post that TR. I'm pretty used to coated blades being a SRKW user. I would expect a few scuffs after that on a coated knife, but it looks like it cleaned up pretty good, and I see no evidence of exposed metal. I know Guy was concerned with some of the older coatings somehow not holding up as expected. I can't remember all the ins-and-outs of that, but hopefully the coating on these new SK lines will solve all of that. Definitely aesthetically pleasing.

The DLC coatings were not actually very protective as far as corrosion resistance goes. I believe he had some troubles with a Cerakote applicator many years ago, where the paint came off easily. He has since been very critical of Cerakote applicators and will only work with someone who is listed on the Cerakote website. These are being Cerakoted by a local company we found through the Cerakote website.

Since it is a paint, rather than bonded like a DLC coating, it can get scuff marks and eventually wear off. Though I have to say, I'm pretty impressed that it didn't come off with all your efforts to clean up the scuffs.

Thank you, TR for rising to the challenge and testing the knife out! It definitely doesn't matter that you aren't a major bushcrafter or outdoorsman. We want a wide range of users to test these out in many different applications so we can get a good idea of how this steel measures up against the others. It isn't a very common steel so all testing helps!
 
... It isn't a very common steel so all testing helps!...

A hint!!! definitely not 1095 or O1 or A2, and that makes me doubt even 52100....


Also, still working with mine, but have a shaving video to upload ;) This knife is a LOT easier to shave with vs the 5.1 :D

Awesome little review, TR :thumbup:

I had it in my head it was an issue with corrosion, but didn't want to say w/o confirmation. Thanks for verifying that :thumbup:

Arrrgggghhhhhhh! The anticipation is killing me! :torn:
 
I'll slap a magnet on it later just to figure out if it is SS or carbon. Something tells me coated is carbon.
I think that you will find that your stainless knives will stick to a magnet as well. Try one of those magnetic strip kitchen knife holders.
Martensite is magnetic. Austenite is not. It depends on the alloy and the structure.
 
I'll get to participate in this thread now since I was lucky enough to pick one up today. :thumbup:
Can't wait for this one to arrive!
 
Woo Hoo!! We scored a 4.1 sample!!
 
TR
My thoughts parallel yours. Hunter and fisherman with young family. I also tend to save and buy higher quality gear and take care of it. I also shoot a 1911👍
I look forward to seeing what else you have in store for your 4.7
 
If that coating were to wear off, try and force a patina on it with some vinegar. For corrosion protection, not to see if is stainless or high carbon steel of course. [emoji6]

So awesome! Way to go! Does this make me the only Wisconsinite here without an SK 4.7?????

If I was in a buying position I totally would have snatched up one of those surprise treats. Does this mean the buyers will have them before the 30 mystery testers? Makes sense since you paid for yours :)

They should all go out around the same time.
 
Congrats! I was distracted today and didn't even know there were sk knives for sale!! That was a cool surprise, excited to see what you guys think!
