The "Ask Nathan a Question" Thread

Given the application, that is almost certainly paper-based micarta. And there would be no reason for them to use asbestos in that application. Yes, that is probably some pretty choice stuff. May or may not be Westinghouse, unless there's a label or it comes out of Westinghouse switchgear, I don't know how to tell.

Yes, absolutely I would like some of that. I'm sure there is some salvageable material in it. If you'll send it to me, I'll send you some scales made from it.

sounds good mang, it will probably be a week or better before I can dig into it but I will get it to ya

Im not knowledgeable with electrical stuff, whats the larger picture of the part they used these materials in? You know, in case I find any thrown off into the weeds on a dirt road somewhere lol.

Neither am I 😆

But, these were in huge steel cabinets of sorts, on top of an old 30 ton overhead crane. All of the power cables ran into this unit and then through different switches that controlled how the crane and its components move.

Ill try to snap a bigger picture after work.

A fuller, as a decorative aspect of a knife, can be added to anything. Doesn't even have to be a knife. I put them on my toothbrush because blood grooves are cool.

Sometimes you see really shallow little fullers added to a design. Those are kind of like a fake ram air induction hood scoop on a car or side vents for a non-mid engine car. Dormer windows that lead to an attic. Decorative but pointless.

An engineered knife can incorporate a fuller as a design element that actually serves a purpose, allowing a stiffer stronger blade for particular weight and balance characteristics by allowing thicker stock increasing the sectional modulus. But it is integral to the design of the knife, not an add-on afterthought.

Some designs lend themselves to a fuller, and the SDFK is probably one of those, but it would require a steeper primary grind, or a wider blade or thinner stock to create a flat for the fuller to exist (you don't want one in the middle of a primary grind). None of those are an improvement to this design, IMO, so I'm not keen on doing it. It runs contrary to the design and intent of this knife which is a heavy duty work knife with maximum bang for the buck. We're not adding a lot of extra features to this pattern. I like the design the way I have it.

Thanks for the detailed response Nathan, I love the way the design looks. I was just curious. Still buying a signature series anyway.
