All About Pocket Knives

Seen this knife for sale and was wondering if this can be somewhat dated by scale color or any other way.Thanks for any info.

Here are photos

That knife is probably 1970's (but after 1973) based on the stamp and the plastic tube that it comes with. Schrade called those tubes a view pak.

And "N.Y." was used only for the first few years after Schrade-Walden became Schrade. Some time in late '70's the "N.Y." was dropped, probably in a staggered fashion as blades got used up.
I have never heard anyone try to date by color of the Delrin but it is an interesting idea.

Thanks for all info.As I was doing some researching there was info about when certain dying techniques were used on the delran and where the scales met the bolsters you could see a color line where the scales were cut,thought someone might Know about that.Thanks all
