I don't think this has been done, closest is the sog revolver.

Here it is:

- a full tang fixed blade, in size like a mora or f1
-A saw, like on the SAK trekker that folds down.
-Possibly other tools?

Heres why,

On this forum, I have noticed something. Recommended is a small fixed blade and a Sak, and a chopper.
Why not combine them, like a FIXED BLADE SAK??:) :)

I think this would be a cool little knife. I am not downing the classic sak and fixed blade concept, I just want new tools on the market.
With the fixed blade you could baton trees down, split wood, drill, all the things you would use a fixed blade for. With the full tang, you lose nothing in strength.The saw used for notching, in shelter building and traps. If their was an awl, you could use it to punch holes in leather, to make clothing and such.

What do you think? Any custom makes want to make this blade?

Take care everybody, thanks for reading my "idea",

I like the thought of a full tang,fixed blade with a saw,I've never tried the revolver,and though I'm sure it's a good design Im sort of turned of by the pivot,even though thats what makes it interesting.

Im not big on sawbacked blades either,so I agree that it would be a very useful knife.Im guessing the saw would have to fold out onto the blade spine,I wouldnt want to start sawing with the knife blade towards me:eek:

Good Idea:thumbup:
 
Thanks for the reply, I overlooked the pointy blade as you are sawing.
Could you have the sheath on the blade while sawing?

I don't see why not,epecialy if designed for a decent grip.

This is slightly different,and may have already been done but what if instead of a rotating blade like the revolver,one made a knife with slab handles that could be quickly unbolted or locked somehow,and placed onto the saw or knife end of the blade? Just a late night Idea :)
 
in the interest ofusing a few moving parts a possible, maybe try the saw attatche to the sheat instead like on a hard kydex sheath, witha removable sleeve that covers the teeth, when the knife clicks home you can remove the sleeve from the saw, and use the handle of the knife as the handle, I don't know I've been up all night just a thought.
 
Interesting idea, but what I see wrong with it is the folding tools in the knifes handle. They would need to protrude enough to get ahold of and open them. Seems to me that this would make the handle very uncomfortable during knife use. If the tools are added onto the knifes buttcap, then there is the need for a larger sheath to carry the extra tools, but at least the handle would be useful without discomfort. It might have to be extended a couple of inches and have a switch, so that the tools could be easily disconnected and the added weight and bulk could be a negative for some people.

Personally, I wouldn't buy it, because I like having the ability to just take the SAK out of my pocket, instead of a bulky edged tool system, including sheath, off of my belt.

The biggest problem, as I see it, with saw teeth on the back of the blade, is that the teeth are usually poorly designed and the blade is too thick. If we took a fairly thin blade (Mora?) and added saw teeth that most would agree are well designed, such as on the SAK's, we might have a winner.

I'm not sure I'd like a fixed blade that basically has a SAK for a handle...worried about the discomfort and getting "swiss army hand" (That's when you grip your SAK so tightly for so long that your hand looks like a bas-relief of the knife).

Maybe a fixed blade with a "hex hole" on the butt to take hex attachments. (love to see the patent application for that...Six Sided Butthole)
 
I agree it is not perfect. I am by no means a knife making, just a dreamer. :)

The thing that draws me away from the revolver, although I have never held one or used one, is the thought of the saw rotating/coming out onto my hand and cutting it while I would be using the knife.

Back on track.......

When I grasp my trekker, the tools that stick out are the bottle opener and the can opener. The saw is not sticking out and won't dig into the hand the least bit. The tweezers and the toothpick also fit well into the handle.

Now, holding my trekker in hand, if the saw would rotate on the bottom and not the top, and be on the non sharp part of the blade side, the part that sticks out- the part that you use to open the saw- would be on the the close to and next to the blades spine. That way you could still have a forward single guard. That is the whole point of putting it on the back, so we can have a forward guard.

To me, a little saw like the one on the trekker is very handy to have.

Now, if the knife is full tang, the bottle opener and can opener could lie right along the tang, they would be in a perfect line. A small grove in the handle would just expose the finger groves. This would solve the problem of them sticking out and digging into the hand.

Also, since the saw is on the back, you have another place to put some other tools on the front side of the tang, opposite of the bottle opener and can opener. I don't know what you would put there, :confused: Maybe a metal saw/ or file? Or nothing at all.

Now, on the back of the trekker theres an awl and a phillips screwdriver. I personally don't think these dig into my hand.

Now, the phillips has got to go, because thats where our wood saw will be. On the other side of the tang, will be the awl, just like on the trekker.

The toothpick and tweezers can stay in the exact location.

Now, I think I have refined my idea. :)

Have a full tang knife, with single guard, on front side of tang, have bottle opener and can opener and possibly another tool or two as there is an available slot, on back side theres a wood saw and awl. Theres a toothpick and tweezers. And the tank slightly sticks out like on the F1. A quickly removable sheath would guard the blade while sawing. Also, I think with the full tang you would be using the saw less. But it is still there for if you need it.

I always saw on the side of my body, so a blade pointing back wouldn't worry me.

Oh, what a dream. :) :) :)

Take care,

Well, I'm new here, but this Leatherman seems similar to what you are talking about.

I've seen one in stores, but I've yet to actually play with it. Its a fixed blade like the Revolver is.

The saw on my idea folds down, not out on the blade like that leatherman. I think that saw on the leatherman wouldn't work as good as a saw such as on a SAK.

Any other opinions, help. I would like to hear from people. :)
 
To be honest I was extremly happy with my Revolver H. The saw was very aggresive, it had an awsome lock up and was very strong all over.
 
I am sure the revolver is a good tool. If I had one and it worked for me, I wood carry it, no problem. I just think, that if a knife came out like the one I am describing, I would be more interested. Maybe I will have to get into knife making when I am done with college to make my idea into reality. For now, truly just a dream. :)
 
Scottman, there has been knives made very similar to what you described (if I understand your description) for many years.

There were some early models from Germany I remember with stag handles and a saw or blade that opened out of the handle.

I tried to locate a pic of one but could not find one.

Oh, I think you would love the Revolver series, they work perfectly, and have for four years now.:p

something like this ?

current model , availiable ex Germany
 
What I'd do is make a long thinner blade with a properly designed set of saw teeth on the back, like a corona pruning saw.

Then I'd make what amounts to a SAK with no K, just a folding toolset, and pop it into a pouch on the sheath. make it disassemblable so users can put their desired tools in it.
 
Not implying anything about the actual craftmanship of those designs and only considering systems:

I've been thinking about that uluchet, and actually, if you think about it twice, it's not that great, I mean it is only a collapsible axe.

Let's say you choose a standard axe of same length and weight class: it will be a bit bulkier (but the open uluchet is not that big) but you will increase reliability a lot, and functionality will be pretty much the same.

About "revolver" knife, I've been thinking too, and gain actually doesn't seem that great:
It's lot like like a folder with a sort of button lock.
Despite the system, most of the effort will still transfert to the pivot. The handle largely open "sandwich construction" means loss in toughness.
Main improvements would be that, the "opposite blade" avoids the blade to clap on your fingers if the lock ever fails, and the construction induce that the stress put on button lock is lower than if it was near pivot, thanks to longer lever arm.
Those would make it better than your average folding knife, but on the over hand, you lose the lower bulk factor since it can't fold.

The german design, as shown by Myal, is certainly ugly, but you get a (supposely) full potential fixed blade, and some folding tools that would probably a bit awkward to use but not that much.

Another design that is quite goofy, but seems to work on paper is that russian "balisong multi tool" (sorry I can't find the pics back): it is a lot like the revolver design, except, instead of having a rotating handle, the handle works as a balisong, releasing one blade while it protect the other one. In theory it would be more reliable mecanisme, but more pivots could also mean higher britleness.

Another idea that seem smart on paper is the system seen on recent leatherman hunting knives such as "steens", were the saw folds other the edge, an improvement other the spyderco vagabond system. But that system probably require too tight fit, and might probably let you down in the field: not robust enough IMO.

Honestly, if I had to choose among all those designs, I think I'd choose the "german" one which is really ugly, but seems the less complicated and most robust. I think many german and/or Czech maker have done that sort of pattern, but those have gone out of fashion, since they are pretty ugly and not significantly better than a fixed blade+a SAK.
