Sam Taylor, aka Mecha, aka Mad Science Forge;

Sam is a pioneer of forged titanium cutlery, and his specialty is swords. His work's been progressing in leaps and bounds, and rustic, hand forged pieces such as the one featured in this thread are now all but extinct. In fact, this one might be the last.

The swords that Sam's producing are increasingly complex, and yes they are all titanium. Titanium has one key attribute of concern to collectors, and that is EXTREME corrosion resistance. Theoretically, one of Sam's titanium swords will last 1000 years. Or more. This characteristic is useful to a guy like me as it allows me to be lazy when it comes to maintenance. However, this characteristic is the least interesting to me, compared with other attributes of beta titanium that have super high value for a brush clearing tool such as this one.

Titanium is inherently shock absorbing. That's probably the wrong descriptor, but conveys the idea well enough. Compared with steel, titanium deadens the feeling of impact under load. Unlike steel, titanium doesn't 'ring'. While the material is springy, it isn't springlike when it comes to feel.

Flexibility is really important for a tool such as this. Fatigue life of titanium is insanely long, so a little flexibility doesn't hurt from a durability perspective. The flex, coupled with the damping effect makes for a tool that hits hard yet yields under oblique strikes without transferring a lot of shock.

Work hardening is a slightly less tangible aspect of this beta titanium. In my experience using this material, (see this thread ) I found that while it was difficult removing the burr from the edge of this material, once I got out and started using it, the sword's edge got more and more refined. It was really weird, heading out with a mediocre edge, and after working the hell out of it, come home with it in better shape. Exactly opposite of what I'm accustomed to.

Titanium is incredibly light weight. This thing only weighs 275 grams/ 9.75 ounces. While it's only 3.4mm thick, it's 22.5" long, so that weight is incredible. Swinging this thing around, well, I could do it all day. It's the maximum length that I feel comfortable using and gives me a lot of reach compared with other choppers I'm accustomed to using, but it's so light that it simply disappears when I'm carrying it around.

Julie Barber, (oye_leather on Instagram) made a beautiful scabbard for this piece from supple, smooth deer hide. The handle has a matching wrap over cord wrap. I love her unique approach to sheath work, you really should check her stuff out. Really great quality.


So, I had a couple hours yesterday to work on a trail alignment that's ready to cut and I was really looking forward to getting out there with this machete thing and get some work done. I was able to record a couple of segments, which you can view in fast forward below. If you want to watch both full 12 minute segments, they are on my Youtube channel. Kind of boring to sit through it all, but I recommend checking out parts and turning the sound up a bit so you can hear this thing hit stuff. It has a unique sound to it which is pretty cool.

Sam, thank you so much, brother! I LOVE using this cutter, it's one of the best ones I've ever used. It's different from everything else I cut with, in none but the best ways.
 
Twas a fantastic write up!
See you on the battlefield, Brother Lorien.

Tell 'em the truth, Lorien: The factory edge sucked! :D

Thanks for the write-up, good sir. I'm glad it's functioning well for your trail-busting purposes, and look forward to hearing more feedback after it's had its ass kicked extensively.

That blade is my favorite chopper yet to come from my humble forging operations.
 
Mecha,

Have you ever thought about offering steel versions of your blades? I like the looks of them, but just not real interested in the titanium, and I wonder if others wouldn't also feel the same.

Either way, you have a great style, and I enjoy seeing it.

I reread my blurb, and realized that it sounded like I was talking about this machete wrt to the edge. I was referring to Titanilor, which had a much more obtuse bevel geometry that I had a tough time getting a slicey edge on. This lil guy; well, there were a couple of spots that could've been sharper- and now they are! Very easy with DMT hones and a strop, due to the thin bevel. It can shave now :) For a working tool, the 'factory edge' was just fine!

Ha! I was just mentioning it as a joke because the final little microbevel on the edge is something that I'm seldom happy with, and often I feel like I'd just uglied the blade up when it's done. I start sweating over the 2000 grit belt as if I was making a critical TiG weld on a thin stainless steel pipe. Some of the latest swords are just polished down to zero, which feels more natural to do and is very sharp, but not as tough of an edge.

Lycosa - No way, steel is just fine, and steel metallurgy continues to advance at a rapid pace, way moreso than ti metallurgy. It's just simply that working with beta titanium alloys allows me to make a large blade/sword that has the sort of eccentric attributes that I want. A great blade or a crappy blade can be made from either! :] I've had the pleasure of handling some steel swords that are just a dream in balance, feel, and performance. The "best" swords I've ever seen personally, in my opinion, are Dan Keffeler's made of CPM 3V steel; just incredible, well-balanced and the power of the swords is blatant and resonant.

Camber - Yes using steel has been considered, and 2x sheets of Hitachi blue #2 (the kind with tungsten) are on hand for the purpose. I'd like to make san mai blades from the steel, but we'll see. Thanks for asking.
 
Sam- A pox upon you! :D How dare you not know that I approve all things blade??!!
I really do. INFI, A2, the CPM's, Titanium.... all outstanding.

thank you Dudley, and you too, Joe. I wish I could work that fast for realz, even still, I'm gettin a little creaky these days
 
I was so excited for you to receive this, I'm so glad you like it, and I'm jacking your nice pictures for my instagram! :D

You have knives that aren't ti? :confused:

Blasphemy! :D


The "Lorien cutting a trail on a 2-liter of Mountain Dew" videos are hilarious.
 
I have a red-bellied woodpecker that works the trees behind the house that sounds PRECISELY the way that whacking did in the video.
:D

Nice, blade, Sammy! :thumbup:
 
You are welcome, Lorien. Keep the videos coming.
Sam- I do own some steel knives. Just for the heck of it. :D
Matthew! Very cool observation! Are you a birder?

I know you'll make good use of them, it's the least I could do!
Thank you very much for your excellent work :)
