History, mentionings from the forums etc.


Extracted from a post[1] by "sal" on the Spyderco Forum:

The Michael Walker C22. A Spyderco, Michael Walker, HP Klotzli collaboration. Early 90's.
First production carbon fiber handle.
First production nested Walker-linerlock.
First production colored titanium.
Only Swiss made production Spyderco.
Custom made phosphure bronze pivot.
The Carbon fiber came from the Sauber F1 race team.
The knife was built for us by HP Klotzli.
My wife, Gail carries one as an EDC.

Extracted from another post[2] by "sal" on the Spyderco Forum:

HP Klotzli came up with the idea for a Walker/Spyderco collaboration. He also swanted to build it. It was his idea to
use carbon fiber and he worked with Michael to develop manufacturing methods. I worked with Michael on the design.
Michael is quite a genius.
HP made the knives for Spyderco. We made the ATS-34 blades in Golden and shipped them to Switzerland. He
developed the carbon fiber and titanium mfg methods. HP does great work.
We thought about working with HP to make a slightly larger version of the C22 Walker. His wife Beah, had drawn a
beautiful larger version by incrementally extending the pattern.

Historic information provided by HP Klotzli[3] (email communication 2009/03/24, informal translation from German):

  • A total of 1165 C22CF were produced.
  • The exact numbers per edge grind type cannot be determined anymore. The Spyderco order consisted of 500x PE and 500x PS.
  • Klotzli delivered knives with "naked" blades to Spyderco. Spyderco did the engravings and numbering on the blades.
  • Glossy vs. matte carbon handles: Spyderco's quality demands were high. Initially only perfect carbon handles with the glossy surface were accepted. That resulted in more than 50% wastage with the carbon. Klotzli then started matting the carbon handles, so that fine scratches (that were unavoidable during production) disappeared.
  • "Klotzli" vs. "Swiss made" engravings on the blade: Initially it was agreed that all three names should appear on the blade: Spyderco, Walker, Klotzli. At some point Spyderco stopped putting Klotzli on the blade (and used "Swiss made" instead).
  • The Klotzlis are not in possession of the drawing by Bea Klotzli of the larger version of the C22.

Other C22s

Information from the Spyderco catalog on the web

Not listed.


The C22 features a Walker Liner Lock and a spear point shaped blade.

The C22 with CF handles and titanium liners were made in Switzerland by Klotzli. Spyderco individually numbered them (exceptions?). Two CF handle types exist:

  • CF glossy (and some without numbers?)
  • CF matte

Earlier produced C22s with CF have glossy (shiny, polished) handles and later ones matte. There are also two types of engravings on the blade: The "Klötzli" put on earlier blades was later replaced by "Swiss Made". There also exist C22CF blades with lasered names and number instead of engraved (in the [1500,1699] range?). C22s with an engraved number in the 1700-1799 range have been reported.

All other C22 variations (incl. CX06) were made in Seki-City, Japan.
