Knife Gallery III
Two Bladed Pen and Jack Knives
Continued
Knives are listed in numerical order by handle material (first digit) and the last three digits of the six digit pattern number. The two blade knives are not photographed to scale, but to optimize viewing within a 3" x 3" frame. Smaller knives appear larger than actual size, larger knives appear smaller than actual size.

020335 Complimentary Letter Opener/Ink Eraser 622357 3 1/2" Brown Bone, etched "ShurEdge"
The 622357 unusual jack knife above right was introduced by Robeson at Christmas in 1910, along with fourteen other patterns. The fifteen knives were prominently featured in a full page, full color ad on the inside front cover of the December 3rd, 1910, issue of The Saturday Evening Post.
I've only seen one other knife with the "ShurEdge" script etching on the blade. I've seen the etch on three Robeson straight razors, however, including one that is featured in the straight razor section of this website.

622409 4 3/8" Swell Center Elephant's Toenail 422414 3 1/4" Ivoroid "PocketEze" Dog Leg
The 622409 brown bone elephant's toenail, or sunfish, above on the left has two backsprings. The large, wide blade rides on both springs, and the small blade rides on one spring. As far as I know, only Robeson made these knives with two backsprings. They also made the pattern with one backspring. The knife is also a swell center pattern. Swell center toenails are much less common than the standard handle die shape.
