The "Ask Nathan a Question" Thread

Micarta is king. It really is impressive stuff when looking at the history of it and the breadth of its uses, even in some critical applications many decades ago for space vehicles and ICBMs.

I do find it nice holding a tool with a handle made from such history. Perhaps this is why I'm most fond of the vintage micarta and the now-elusive ECAM. Some of those sheets may have been earmarked for a lunar lander at one point. Or maybe generators at the Hoover Dam. Who knows...

And it's grippy and looks cool.

And ideal blade would have been a little less wide, viewed from a resistance to whip in impact perspective on the hard targets. It was wider than it needed to be for that.

However, the primary grind angles required for these cuts are relatively narrow and they stack up to a wide blade. And it needed to be double-edged with the leading edge used on hard targets and the trailing edge thin and very sharp and used for things like meat. The ideal blade would have actually needed to be even a little bit wider than it was to have the ideal primary grind angle that we use in cutting competitions. The only fix to address that would have been thinner stock, or the width that we had.

Thinner stock wouldn't have been better.

It's a balancing act that involves cutting geometry, durability and kinetics. The geometry is what it is because it was the best balance that gave the power and cutting capability that we needed in a good form factor and weight with the perfect combination of weight and length for the application, while being very close to ideal on the grind angles. Within one degree of optimal.

There were no aesthetic design considerations. It is a pure high performance competition cutting sword and it's one of the most powerful cutters you will ever come across. There are very few swords that can cut through a 2x4 in one hit without being damaged or destroyed, and this sword can do it all day long.

one of my CPK grail.
really wish i got one in the preorder.
too bad K18 is retired.
 
Nathan the Machinist Nathan the Machinist what system do you use for your tumbled finishes on knives?

I reload and have a vibratory tumbler (that’s what she said!) with Walnut & Corn Cobb treated media, as well as a rotary wet tumbler with stainless steel pins (maybe I’ve got some ceramic media too, but can’t remember now if I ever ordered it or not).

Curious if one of those systems would work for a home remedy repair for visible and scuffed/scratched surfaces?

What are your thoughts?

Thank you sir!

Depends on whether it'll fit in the tumbler ;)
