Shumate "Model Numbers" - Reground??

Does anybody about the "model number"s on Shumate razors?

I have two marked "0175". One has conventional stabilizers. The second is shoulderless. The point is different too. I would expect "0175s" to be the same. :shrug:

Could the shoulderless one have been reground? Or is "0175" more of a date code or maybe indicate the craftsman that built the blade?

Steel batch code maybe ???? like the TI system???? :shrug:

That was probably the number stamped into the blanks during the forging process, before they were ground into the various styles. As Glen said a batch number, but I would think that it was more of a stamping batch than a steel batch(heat number).
