    Logan Pearce Wrench knife, anyone ever seen or had one.


    ADVERTISEMENT
    I saw a pic of a 13"/16" wrech that Logan hammered into a blade, any idea if these would make a good user or is the steel they use not a good choice for makin' knives?

    I would imagine the steel would have to be annealed, like when Anza makes knives from files.

    I had not seen these before, thanks for posting. I'd actually love to try one out.

    Cool looking knives. It will depend on the brand of wrench, but in general the steel wrenches are made of is selected for toughness over anything else. There may be a moderate amount of carbon, or in the case of high alloy wrenches maybe a fair bit... If they are just made from random wrenches I would put these in the class with railroad spike knives...they will probably open letters for a lifetime or two just fine. If the maker knows what alloy the wrenches are, and is selecting high alloy wrenches and heat treating them properly, they could be very good knives

    A lot of the old Williams wrenches and old KD wrencheds were drop forged but I don't know what kinda steel they used, I can see where these might make great slicers but may be to brittle or hard for camp use.

    Still it's a great idea, I'd drill/mill out the flats on the box end, it could make a great Kermbit.

    Craftsman wrenches are as well, those should work.

    Kind of nerdy for me noticing, but in the newer game Battlefield 3, one of the main Russian characters has what appears to be a bent wrench knife on his vest.

    I'm sure as long as there have been forged wrenches someone broke one and hammered/ground it into a blade, I'm surprised I've never seen one and I was a mechanic, heck I've made more customized wrenches than I can count. Never thought to turn one into a knife.

    Anyone with more understandin' of metallurgy wanna chime in as to the characteristics of the type of steel used in wrenches it would be appreciated.

    I made one ages ago for my mechanic nephew heated in the forge and beat it into a knife quenched in canola worked great.

    Oh wow. I didn't expect my work to end up on here. lol. Sadly, the top and bottom wrenches didn't make very good knives. They were from cheaper wrenches, but it had more metal for me to work with. I had hoped that I could harden the metal, since it came out looking like a better knife(in my opinion). The middle one is made from chrome vanadium which wasn't too hard to harden and seems to keep a pretty good edge. The only thing I don't like about them is the lack of metal that I have to start with, but they are also longer than the other two in that picture. The picture itself is kind of old, here is what my wrench knives look like now:



    They are pretty fun to make though. I never imagined it would circulate like it has or I would have taken a better picture. lol.

    What wrenchs do you find make the best knives?
    Lookin' forward to seein' more of your work.

    Might be kinda hard on the hand when using the wrench end.... *sarcasm*

    Being a headgear, that is a very cool project.

    No problem! I only post my work on here ever so often. I've been meaning to post more, but I really haven't had a lot of time to in the last few months. Honestly, I haven't tried a whole lot of different types of wrenches out. I try to keep all of my Remnant pieces as affordable as I possibly can. What I did was gathered up a few of the locally sold wrenches and tried to get in touch with the companies that made the tools to get an idea of what metal I was working with. Some of them actually helped me out, but most of the edge testing feel on me to heat treat edge of them using different temps/quenches. I ended up just going with Stanley wrenches as they aren't too expensive and the chrome vanadium seems to hold a good edge.

    I figure if money was no object then I would go with a much more expensive wrench which would probably have more metal on it. Which means as much to me as being able to heat treat the wrench. It's almost pointless to be able to heat treat one if its going to be as thin as a fillet knife when I'm finished, unless I'm going for a fillet knife. lol. Again my wrench knives sell for $30 at the moment, so you can imagine how limited my research on the wrenches were. I figure if I hadn't had such good results from the chrome vanadium wrenches, I probably would have stopped making them.

    In the end they are super fun though. It's nice to make something like that just to take a break from hunting knives or carving on art knives. Plus who doesn't like cutting their hand while tightening a bolt? :P

    Back to the humorous side

    This has the be considered the first "box" knife. I like these better as the open end knife falls off your finger.
    In England it would be a spanner knife I suppose, but what's the box end of a spanner called, since it doesn't span.
    Ah heck, I Googled it and it's a box spanner; not quite as quaint as spanner. So then these are "Box Spanner Knives" use with my blessings.
