The mollusk applies nacre in layers. Most shells are not large or thick enough for knife handles, so the shells are broken into pieces and layered with adhesive. Mosaic is larger pieces laid out and glued together. The laminate that I use has a very thin layer of premium shell sandwiched between a M...

Angelo Campolin, Sr. was the production manager for Mauro Mario. Whether there was a MM manufactory, I don't know. Perhaps the brothers were simply contractors. Perhaps Campolin made their knives. I have not researched this. There are some who have, but they guard their information because they thin...

It is indeed a Latama. Perhaps it was an early one- before the patent was issued. Less likely is that it just didn't get stamped..

Show us a picture of the knife.

Same process as above. Get it shaped, harden, and temper.

I haven't even unboxed it yet. Started clearing a space for it in the shop, but still have to learn how to use it and what it will/won't do.
This one is a diode laser-sort of between a CO2 and a fiber laser. It will do some metal engraving. If I get it figured out, I'll probably get a fiber laser.

I thought you were talking about little coil springs, like used in knives.

3/32 can be successfully torch heat treated, Quench in canola oil.

Why would I want to post pictures of my new design?
The Chinese might steal it!

It can be done. Unfortunately, small coil springs are too thin to reliably heat treat without a heat treat oven. The steel heats and cools too fast without a controlled atmosphere and even heating is a problem. In theory, if the spring is common high carbon steel- heat to cherry red and quench in wa...

I won't be accepting new work for at least a month.

Unless you can properly heat treat the spring, the answer is "no."
And, from your question, I can tell you can't properly heat treat the spring.

It's not a switchblade if it doesn't work. The knife may be worth more than the added repair cost, and it will sell quicker if it works. Here is an example of pricing. There may be additional problems encountered during the repair-such as blade tip peeking/sear repair becoming evident after spring i...

No, I'm pretty serious about it.
I just bought a laser engraver, too!

No, you were there. It's been a while back. I was sharing a table with Walt.
