Here is my initial review of the edge that came on my Rex45 Para2 in greater detail that I just posted on the Spyderco Forum.
First: when I saw it, I didn't go immediately "YUCK" and decide to either sell it or promptly give it an adequate edge. Ok, I freely admit, I am one of those Edge Junkies that are joked about.
So, upon initial edge review here is what I observed: The apex is clean with no chipping visible under a 4 power magnifying glass. The cutting edge profile and cutting bevels are quite even along the full length of both sides of the blade. The grind marks are exceptionally even, even at the difficult tip and ricasso areas. In addition, the grind marks do not show the common signs of chatter (but those usually show up best during the first stropping/sharpening). The main bevel grit used seems finer than often found on normal PM2s, being approximately 30/40 micron in size. That is probably due to some combination of either a finer final grit being used, or a gentler touch by the grinder. The edge has a touch-up ultra-micro-bevel that fairly evenly covers the length of the cutting edge. In addition, the angle of the micro-bevel is only about 2 degrees greater than the bevel, which is wonderful. It is probably that final process that also gently polished the blade/bevel shoulder. All together a wonderful job!
Other than two custom Japanese kitchen knives(one in Hap 40, the other one in PS60) , I think that this Sprint PM2 in CPM Rex45 is the sharpest factory edge that I have ever received. It actually (barely) splits my wife's dry ultra-fine hair, which is way sharper than shaving sharp.
My favorite kitchen knifes are in Hitachi Hap 40, so I am looking forward to putting this knife into use!
Sal , Someone in management deserves thanks for devising the final sharpening process of this batch of Sprints, and some also deserves praise for a very craftsman-like job for carrying the sharpening process out!
Thank you very much!
