When did Cold Steel Rifleman hawk size change??

[walkbyfaith777]

Can anyone tell me when Cold Steel changed the size of the Rifleman hawk head? I bought mine about 2 years ago and use it as a template to make my leather sheaths. I recently had a Rifleman custom angled belt sheath not fit properly. I compared the customer's older Rifleman hawk with mine and sure enough, the older one has more distance between the handle and cutting edge - about 3/8" difference. I had no idea there was a difference. I would like to be able to sell the appropriate size to customers but I need to know approximately what year Cold Steel changed the size. Does anyone know???
Thanks

If anything I would guess it would be when cold steel changed from having the head with no setscrew hole to having the set screw hole added
Just a guess, could quite possibly be wrong
