"Washers": Phosphor bronze (not washers per se - explained later)
Held together by hex screws.
Positives:
+ Big, solid folder with hardware to match. Heavy-duty hardware and liners, and a dual pivot (adjustable from either side) with large stop-pin.
+ Nice thick blade, shallow hollow grind to a wide primary bevel. Entire blade is beadblasted (including swedge and primary bevel) except for the satin-finished flats (with maker's mark apparently in ink-type).
+ Blade is centered when closed. No blade play, horizontal or vertical when open.
+ Action is very smooth, there is a slight "click" as you overcome the detent, and it glides open until the liner-lock engages with a satisfying "schwack!". Can thumb-flick it open quite easily.
+ PB washers/"liners" -- Ron basically took some PB sheets and cut them to shape (of the handle) around the tang and beveled the edges slightly. These aren't really washers, but they work very well.
+ Single, RH thumbstud - very wide and comfortable, and well-placed.
+ Edge is substantially sharp. Slices paper with ease, but won't pop hair.
+ Solid liner-lock, locks up 85% just at the edge of the tang. Scallops are even, neat, and work well.
+ Jimped, raised thumbrest. Naturally placed where my thumb rests and VERY grippy.
+ Ergonomics are very well thought-out, sits nicely in the hand, secure, but without being too restrictive re: grip. Slightly curved downwards, predisposing it to forward grips. Index finger choil is very wide and smooth.
+ Bolsters - brushed, satin finish.
+ Deep-carry pocket clip (stainless)
+ Green Micarta scales are flat, satin-finished.
Negatives: few minor issues - mostly fit/finish:
- Couple of places where the counter-sunk screwholes are slightly uneven, hardly noticeable. Similar very small mistakes are find here and there on the liners.
- sharp edges on inside and outside of handle liners/scales and scallops - took me 5 min to fix.
- Thumb-rest can be abrasive. Scrapes the hand as you go in and out of your pocket. Perhaps blending it into the rest of the blade might help. Mostly I think it's just the space the folder takes up.
- Slight mis-fit of one of the GM scales near the very butt. Gap is noticeable, but cannot even fit a piece of paper in it.
? - secondary bevel is slightly uneven in width near tip and near tang of blade.
? - Prefer a slightly stronger detent.
Frankly, I'm not sure how to sharpen the tip properly on my knives - they always end up broader and wider there. This doesn't detract at all from functionality.
Suggestions:
First, I think actually beveling all the edges of the folder, especially the bottom edge, and then rounding the handle (swell) overall would make it more comfortable to use. As it came, IMO, the edges were too sharp for prolonged use, especially for such a thick folder (makes it more noticeable to me). For the linerlock, another option other than the small scallops, would be to make one large scallop with a wide, convex file - more comfortable and still gives good grip.
I think a choil right behind the edge would suit this folder model admirably - It would only require a less material cut from the blade tang and reshaping the forward end of the handle and bolster. Perhaps making the primary index choil slightly smaller?
OVERALL
This is a beast of a folder. It has its minor flaws re: fitting, but mostly things that just take practice or time to fix. I think comparing it to the original Spyderco Chinook might give you an idea of it's size and weight. The blade maintains its thickness until tapering smoothly 1.2 cm away from the tip. The liner-lock is substantial and very solid - no bladeplay.
All in all, this is a bargain for a custom, working folder.
