201MF Tri-Angle Sharpmaker
History, mentionings from the forums etc.
Some information from Sal Glesser posted on the BladeForums:
The 201 was narrow, no flairs at the bottom, 40 degrees angle only, 2 brass safety guards. We realized early on that it was too narrow and added flanges on the front half for greater support which was the 202.
