Spyderco Reveal #13 Now OnlineH. Clay AaldersNewsfeed·1 Comment··9 views Spyderco releases periodic “Reveal Books” of knives that are going to be released shortly, rather than make announcements a year ahead of production. The latest, Number 13, is now online. Click Here to Launch. As you can probably guess from the feathers on the cover, Lightweight models are featured prominently. I am personally interested in the Native Chief in CPM SPY 27 steel.
