Re-discovering stainless steel handles like it was 1982 again!

15-20+ years ago Spyderco had a fillet knife project in the works with Phil Wilson, the King of fillet knives. I remember seeing several generations of prototypes, maybe two sizes, but the project was put on the back burner, perhaps due to the then perceived high cost. Today, with renewed interest d...

Hi Sal:

Did you say where the Chaparral SlipIt will be made? Taiwan or US?

I believe that Gerber began using chrome plated M2 (from used power hacksaw blades) in the late 1940's if not before WWII when they began in the late 1930s. The same chrome plated M2 was used in the fixed blade hunting line in the mid-1950s.

It is with tears in my eyes, a smile on my face, and sadness in my heart that I remember your kindness, warm friendship, and generous nature that created memories I will never forget. RIP

How about a C215 Euroedge?

https://www.spyderco.com/catalog/details/C215G/1018

Too bad Spyderco discontinued the BEST (SpyderEdge Pointed, K14S) of their Z-Cut Series for 2022. Dunno why.

If you are going to count the non-Spyderco Tak Fukuta Ceramic, then the Solo Titan should be added to the list as well:

Also there are three types of 440C used; wrought, cast (dendritic), and MIM.

I believe that MRS-30 was the steel that Al Mar used for his introductory series of knives. He called it RS-30. I wonder if the M stands for Masahiro. The only other steel missing is AUS8W which was used for the KX05 Sashimi (Yanagiba) knife: https://www.spyderco.com/catalog/details/KX05/Spyderco-Sa...

The walk is smooth as silk and the talk loud and crisp. Perfecto!

Perhaps Spyderco's maker of Boltaron sheaths, especially as they may have the tension adjusting bolt.

Coulda, Woulda, Shoulda, ... What if Sal had contested the patent office's "obvious improvement" and convinced them accept his "claim". Then, instead of fighting everyone in court over their infringement (use of his pocket clip patent), he instead decided to license his patent an...

All folding knife locks wear as their interfacing surfaces make contact. As a lockback is opened and closed both the tang and the rocker arm will wear down (reduce) and the rocker arm will no longer be flush with the liners/blade. It will ever so slowly sink. This is part of normal wear and tear wit...

Also a good list of subjects. I'd like to add one out of the chute; can the advantage of a swedge be measured? sal Sal, are you referring to the type of swedge Ed Schempp used on his competition cutter that he claimed reduced resistance when cutting rope, etc.? This idea is also used on some Japane...
