At first glance you might think this is just another Ferrum Forge run of knives. But when you see that the blade steel used is a very rare commodity called SM-100, you might think again. Elliott Williamson had no choice but to work with this very rare commodity after hearing how hard it is to work with and even more difficult to work with. Not to mention the price tag is stout. These are a limited edition run of 100 and no more. The Ferrum Forge Stinger knives have a tumbled titanium frame lock handle with anodized pivot and bent pocket clip. Per usual with FFKW, it comes with a steel lock insert with integral overtravel arrestor and Hoback rolling detent. The FFKW Stinger's SM100 blade is anodized (color will vary) and will have a caged bearing pivot and flipper tab for easy deployment. The Ferrum Stinger comes with an S3 hard case for investment protection.
