Our Block Plane Blades are available in Two Widths: 1-3/8"
for Stanley-Style Low-Angle planes and 1-5/8" for the 9-1/2,
And There are Two Slot Configurations: 5/8" Wide Slot for
new(er) Stanley planes and 7/16" Narrow Slot for the Old(er)
And to further muddy the water, you have two alloys to choose from:
Our High Carbon or Cryogenically Treated A2* Tool
Steel. (I recommend A2 for all you bamboo fly-rod makers. It
holds up much better to the abrasiveness of bamboo.)
Get it? One of these eight choices should be right for you but
if you need more input, give a call: 888-282-5233.
*A2 blades have an "A" in the part number.
