I know the adage about Schrade and records, but is there an established time period when Schrade introduced pattern number stamps on blades? I’ve tried to do a little research but I haven’t come up with anything.
I ask in part because I just picked up this Schrade Walden 233 that doesn’t have the pattern number stamped anywhere. The tang stamp indicates it was made between 1946-1973 but that’s a broad range. I thought the timing of the introduction of pattern numbers could help me narrow the range.
I think the handle is Delrin but I’m confident in my ability to tell the difference.
Timing of pattern numbers?
Re: Timing of pattern numbers?
If it has Delrin handle,made from 1960 on to 1973.
If you cannot see pins through bolster 1959-60 to 1973.
You can see by my reply Delrin and the Swindon System was introduced around the same time.
Someone else might have a more exact date.That's the best I can do.
If you look up the research at the top of the page it might give the time line for you knife.

Re: Timing of pattern numbers?
I can clearly see the pen in the bolster in the fourth picture so this knife was made prior to the introduction of the Swinden system which was circa 1960 to 61 and it also appears to have Delrin handles. So I would say this knife was made right around 1960 give or take six months one way or the other. That is just about as precise as you can date a Schrade, in fact more precise than probably 80% of the Schrades that are out there. Upon reconsideration, I think a more precise guesstimation would be that this knife was made in the first few months of 1960.
It is a nice knife and interesting in that it is made in the midst of two transitions, the transition from through pin to Swinden construction and the transition from bone or early composites to Delrin.

Re: Timing of pattern numbers?
It's pretty easy to tell the difference between bone and Delrin® (or other synthetics). Use magnification if you need it and look for the haversian canals that bone has. (they're the dark spots where the blood vessels & nerves ran through the bone).
I can see (as Dale said) in the 5th picture that the handles on your knife are Delrin®.

Re: Timing of pattern numbers?
I think your knife has been dated pretty well by the above posters, but that does not answer your question. Somewhere in about 1952 to 1955 (and this is a definite maybe) they added "U.S.A." to the tang stamp and also the pattern number. Your pattern number (it would seem) has either been worn away or just missed getting stamped. That clip blade would also have been used on an 834 open stock, I think.
Re: Timing of pattern numbers?
Thanks to everyone for all the answers. Both helping to date the knife so specifically and to the question of when pattern numbers were added. Oh and even the unanswered one about the materials.
It’s pretty cool that this knife has the newer delrin and the older pin system. And that because of that it can be dated more specifically.
I originally bought this one with the plan to resell, but I may have to keep it.
