Forgive me, please.
To those who've mentioned "saving weight" and a 2 blade version of the 301 being "more pocketable" ... is less than half an ounce weight savings between the 3 blade vs 2 blade or the knife being roughly 1/16 inch thinner
really going to make a difference in how "pocketable" it is?
I can understand wanting to save a little by eliminating the Spey, and putting that savings toward a fancier cover material. That makes some sense. (although I doubt the savings will be all that much)
But to say it will be more pocketable?
That makes no sense.
I compared the thickness of a Buck 373 (same knife as the 303; a 3 blade 3 spring medium stockman) to a Case 22087 (2 blade Jack Knife) that I have.
I thought it would be a fair comparison, since they have the same closed length.
The bolsters are for all practical purposes, the same width. There
might be less than 1/64 inch difference between them. This difference could easily be caused by the amount of bolster polishing when the knives were made. (The Case is the wider of the two)
The 373 has wood covers, with swells, so it is thicker overall than the Case, which has flat covers with no swells.
(See? Full disclosure

)
The point being, a 3 blade 301, is likely to be as broad as a 2 blade knife with the same closed length from another maker, depending on covers, of course.
(Sorry, I don't have a 2 blade Jack the proper size to compare to a 301.)
