Robeson Shuredge 2 Blade Folder

[Pile Driver]

I just got this knife today at a flea market, I believe it's pre WWII but its just my own speculation. I am unable to find this knife anywhere on the internet, on the reverse tang it has the numbers 622. That search yields other Robeson style knives with heavier bolsters. Anyone have any info this knife? Or on Robeson Shuredge as a name/maker?

Nice oldie!

I found a cool informative post on a knife collection forum that provided the following information:

The numbering system of "622" corresponds to the following:
First Number is scale material -
0 – Metal, Aluminum or Stainless Steel
1 – Black Composite, Ebony, Cocobolo Wood
2 – Rosewood or Walnut
3 – Black Pyraline (Slick Black)
4 – White Composite or Ivory Celluloid
5 – Genuine Stag, Saw cut bone, Saw cut Delrin
6 – Jigged Bone, Delrin, or Black Plastic
7 – Pearl or Abalone
8 – Swirl or Single Color Celluloid
9 – Gunmetal, “Shur-Wood” stabilized wood
C – Celluloid, Cracked Ice, or Christmas Tree Celluloid
G – Gold

Second Number is the number of blades -

Third Number is the liner and bolster material -
0 – Combination handle liner bolster
1 – Steel liners and bolsters
2 – Brass liners, nickel silver bolsters
3 – Nickel silver liners and bolsters
5 – Special
6 – Iron liners and bolsters
8 – Steel liners and bolsters
9 – Stainless steel or chrome plated The remaining two or three numbers are the factory pattern numbers.

And as far as dating goes:
"Many Robeson knives were stamped with a variation of ROBESON CUTLERY
CO or R.C. CO from 1891 to 1940. From 1911 to 1940, the well-known
stampings of ROBESON SHUREDGE ROCHESTER and ROBESON
SHUREDGE USA were used, with “Shuredge” in script. From 1940 to 1965 the
mark was ROBESON SHUREDGE USA in all block letters."

So to conclude - I have a 2 Blade Jigged Bone knife with brass liners and nickle silver bolsters dating from 1911 - 1940 so I was right about it being pre WWII!
