How'd I miss this thread?
I agree with some of the posters above - it's a novelty knife, like many others Shun/Kershaw produces. The recurve design is similar to some of the Kershaw "tactical" knives, in fact. Sharpening would require a round or triangular rod; the Sharpmaker would be about ideal for this application.
bishop - welcome to the forums. In what context did you work on the Shuns? Have you also noticed edge chipping on the knives? This has been a problem on some (not all) of mine.
This info is for those interested that may have these knives and my experience with them.
It may help in prolonging their shelf life.
Thanks for the welcome Dakki!
I sharpen knives as a business. Have been running across this particular run of Shuns and they are almost identical to a series by Calphalon.
I researched some and turns out the cores have a high amount of carbon, so no dishwasher, no water soak, no drip dry.
Hand wash and dry only.
Its a spinoff of Onions Spec Bump type knives, a bit milder bump, the heel I'm not sure what for.
I collect knives as well, and have the Spec Bump .. great folder and tactically a nice slicer as it gets to the meat with that belly.
You can sharpen them on a gritted wheel with some hand movements, a sharpmaker (will take time to bur), or like I like, a concave stone from a WEPS system for the recurve.
You can see the edge even from Kershaw is not totally consistant, it fattens in the recurve, but no matter, it'll cut, just like a hawksbill.
Chipping and pitting, on the core edge, polish and rust on the spine and handle.
I'm thinking the damascus is just an overlay and the VG-10 may be VG-1 on this particular line.
Not sure.
I'm guessing the price point would tell.
The Calphalon clearly state VG-1 and warns no broiler, no freezer, no dishwasher, no drip dry.
Problems are identical on both lines so would not be surprised if Kershaw is making both.
Calphalons I worked on were labeled made in China though. Shuns Japan. Parts? Assembly?
Edge/Core are pretty much the same in hardness, just the handle felt any different and not by much, very similar.
Same amount of pressure and grit types on both to get some bur.
