This was from a friend at BFs
"I've found this scan to be a good one to show anybody who asks about Schrade bone jigging. I've discussed it with other Schrade collectors, and although we do not know for sure, we think this information is a good guess.
The pic shows 12 knives, and 4 types of jigging.
The three at upper left seem to characterize the oldest jigging Schrade used. The knives with it often have the old "arched" tang stamp.
The three knives at upper right may be from after George Schrade invented his jigging machine. I suspect that machine may have done the jigging for New York Knife Co. also, with slightly different settings!!
There seems to be a period when this "basketweave" style was tried out on the knives in the lower left. I think it was hard to maintain the pattern - notice how confused it is on the third of those three knives.
It's not as common, and I'm sure it precedes the last "Peachseed" style on the knives at lower right, which was used into the Schrade Walden period, up to sometime in the 1950s or so. I wish I could confirm some of this, but for now it is just a semi-educated guess!"
