Layered titanium alloy katana blade

Thanks to everyone! Next one should be available for the passaround I've been threatening to do for quite a while now.

Tatami mats, standing bamboo, non-standing bamboo, saplings, broomsticks, water bottles, heavy cardboard tubes, phone books, splitting firewood...pretty much anything that is possible to cut. :D It wouldn't be getting sent out to be babied.

No firewood or water bottles

Firewood and water bottles are not Katana test mediums

One because it will damage any katana blade and the other because it is silly :)

Water bottles are one of the few targets we pessants can afford!! Also empty liter, 2 liter bottles, gallon milk containers and other heavier containers like tops gallon apple juice (much harder to cut).

I find it fun to cut a row of bottles to check angles, speed and ability to cut multiple times without upsetting the base remaining.

I would love to try some of my big cutters on a tatami mat target! Including some of my axes and my one sword (a heavy ungainly thing).

I think water bottles are a bit silly also. Splitting firewood is also silly, but I'm sure the blade would be ok. In truth I like cutting big green bamboo more than anything else, the bigger the better.
 
I chopped my MechaTi into something hard and it took some damage...

...which I fixed

I've used this machete plenty since then, and the repair has held.

Titanium is amazing stuff.

Looks like you just massaged it back in line and touched it up?

Big green bamboo is a wonderful thing

The noise it makes is wonderful

Dry firewood is asking for the pass around blade to do more than a katana was meant to do

All right, splitting firewood is off the list. Doing the normal cutting job of a katana, and doing it well, will be a fine mission for the blade.

Great job on that

I think Lorien's blade hit a rock in that instance. That particular machete is one that has the "third" type of heat treatment result, and has a sort of strange plastic feel - a phenomenon of the Ti Nb alloy (I know what produces that result now, but wasn't sure at the time that was made). It will bend as in the photo, while a "normal" one would likely disintegrate some of the sharp edge off and would lose some material, but not deeply so. There are only a couple of them out there like the one Lorien has.


The passaround sword will have this stuff as the edge, same as the sword in this thread:


Took no damage and still sharp, cut a lot more than in the vid, a blade that was under 1/8" thick at the handle and tapering thinner toward the tip.

Practice cutting with a sword or long blade is very fun and is extremely satisfying as far as refining body mechanics. It's been a major reason for making these things since the beginning, tough, quick blades with which to practice cutting.

Just curious, what version of heat treat did you use on the Turbine blades?
