Does anyone know the time frame when Schrade Walden put Pat Pend on their blades? There is also a number below the Pat. Pend., is that the patent number? Does anyone have an idea as to the date of this knife? I haven't seen one with Pat Pend on it before. But I don't have a lot of the 15OT. Codger, LT, Larry, can anyone enlighten me on this knife?

Thanks,
Dale

The patent was filed on August 7, 1964, and the design patent issued on November 9, 1965. That fifteen months is the time frame for the actual production of the patent pending knives, plus any produced before the filing.

Serial #11837 retailed in 1966 at a USAF BX.
Serial #58668 was a Schrade Walden, but did not have the Patent pending stamp, therefore it was likely made after the patent issued in November of 1965.


The number is the knife's serial number.

I have several with Pat. Pend stamped on them, and one with it etched on. This was one of Uncle Henry Baer's designs, and he/they felt it was unique enough to warrant design patent protection. WHile the knife first appeared in the 1964 catalog, it likely went into early production in mid to late 1963. There is a one year time window between first use and filing for a patent to be allowed. After the patent was issued, they discontinued the Pat. Pend tangstamp. You will see this mark also used on knives sold to Sears with the Ted Williams signature etch. This was before they started marking them with Craftsman tangstamps.

Any other questions?

So my knife with the Pat. Pend. was most likely made between August 7, 1964, and November 9, 1965, roughly?

Thanks for the fast reply and all the info.

Dealing with the "possible", the pending stamp could have been used earlier than the filing date, but no more than a year earlier. So we might say that the stamp could have been used from September of 1963 thru November of 1965. Your number (#33201?) would be more than halfway between those dates, so likely was made in early to mid 1965. Without the actual factory production records, this is as close as we can guestimate.

Speaking of stamps and etches on Deerslayers. ever seen this one?
 
That is the one and only Margarita Deerslayer. It was found in a mason jar under Johnnie Carson's porch by Ed McMahan.
 
It actually is a sample from the Schrade sample room. Built on a low numbered blade, remember that this color was in vogue in 1963-64. Cars and trucks, house paint, this green was hot. Remember Jadite Fire King tableware??
 
Codger,
I must say I am really impressed! To have the production date narrowed to a 26 month period on a knife that is 40+ years old is amazing! Great job! :thumbup:
The only knives that I can date that closely are ones I picked up personally from Al Mar or Les de Asis. Of course I didn't keep records so I may not be that close on those. Too many dead brain cells!

Thanks again for your impressive research!

Accolades go to Larry as well. Without his help in digging out the patents and other needful research, much of the known production details would still be obscured from us. And new info is coming to light every week. Several other collectors have helped, sometimes just by the questions they ask, and the knives from their collections they show me. And kudos go to the "survey tool", eBay. Some sellers go to great lengths to show the 15OTs in detail, and are willing to take the time to answer my questions.

Here is another early one, the Schrade-Walden tanged Sears 15OT Ted Williams (no, not Craftsman!) in it's original package, and yes, it is a pending stamp as well.

This knife has no tangstamp, nor a model stamp on the reverse side. I have seen several (not end of days knives) with no tangstamp (Sterile? Covert?). This one has the tangstamp etched on the right choil, but still no model stamp. The bottom left picture is one with no stamp or etch. Bottom right is the first Schrade stamp (post 1973 1/2)


This one is a Craftsman SFO with the usual blank shield, "Craftsman U.S.A." tangstamp right (also seen with the tangstamp left), read from the blade tip(also seen read from the handle). The odd part is the etch on blade left. "Old Timer Premier".


OK, I know I am boring you, so here is the last one. This particular knife has no tangstamp, but an identifying blade etch. It is a private issue made in the 1960's for the kitchen cutlery supply company Zylco, a division of Rena-Ware, and belonging to the Zylstra Corporation of Spokane, Washington. This company employed door to door salesmen, and the hunting knife was a customer bonus when they bought a set of knives and gave three referals.

The tang of the ones that were stamped read "HANDCRAFTED" "ZYLCO" MADE IN U.S.A." (with serial # 030490). Date of manufacture is unknown, but they were most likely Schrade Walden knives since they are serial numbered. It has a black delrin handle, brass rivets and blank brass shield, and came with a standard five rivet folded sheath in black.

This earlier Zylco knife has a left tangstamp of simply the serial number,“020078”, and a right blade etch of "HANDCRAFTED ZYLCO" over “MADE IN U.S.A.".


Hokay, I'll return you to your regularly scheduled programing now.:D

Hey!...Hey!...

Arnold loses 1 point for hitting below the pivot joint...er, belt...:grumpy: :D

Good thread...very interesting pictures. The Teddy Ballgame knife is very cool indeed. :thumbup:

Bill
 
How many of you have A Ted Deerslayer? Are Arnold and I the only ones? Pics anyone?

Codger
(knives that fold on purpose? Why?) :D
 
I thought I'd add that while looking at my Schrade-Walden Pat.Pending No serial number, after reading this thread, I got a pleasant suprise,very faintly etched on the blade was the Teddy signature.Codger says most are this faint so you might want to look closely at your knives.Arnold
 
FIXated on folders...that's very clever there Arnold. :D

You guys are lucky to own those...I'm feeling some jealousy creeping into my usually pure wolfly intent. Even for a FIXED blade.

This knife finally arrived today and I was impressed. I had not expected both the knife and sheath to be dead mint, but they were. Given their ages, I expected the blade to be pepperspoted, and the brass to have verdigris. I had to look hard to find tiny handling spots on the underside of the handle tang to verify that it was indeed a carbon steel blade, not stainless like some of the Craftsman SFO 15OTs I have. The combination of bowling ball black delrin handle and all brass furniture makes for a very striking appearance, as you owners of the Schrade Copenhagen knives well know. Since this SFO predated the Copenhagens, perhaps a retained sample of this Zylco knife, maybe even this very one, was shown to representatives of the tobacco company when deciding on the Copenhagen color scheme.



This private issue (Special Factory Order = SFO) was made in the 1960's for the kitchen cutlery supply company Zylco, a division of Rena-Ware, and belonging to the Zylstra Corporation of Spokane, Washington. The tang of one I saw reads "HANDCRAFTED" over "ZYLCO" over "MADE IN U.S.A." with serial # 030490. Date of manufacture is unknown, but it is most likely a Walden knife since it is serial numbered. It has a black delrin handle, brass rivets and blank brass shield, and came with a standard five rivet folded sheath in black. This earlier Zylco knife has a left tangstamp of simply the serial number,"#020078", and a right blade etch of "HANDCRAFTED ZYLCO" over "MADE IN U.S.A.". The "Pallidin Black" sheath has five brass rivets and a brass retainer snap, very complementary of the brass furnished black handled knife.

PS- A thought on these SFOs with serial numbers.... I am thinking that the number is not knife number 20,0078 made, but order number 02, knife number 0078. The other one (#030490) is SFO order number 03, knife number 490. Does this make sense?
