407. Model 630 (aka Princess Dogbone)

This is a very rare Victorinox knife which actually doesn’t have own name. Design of scales is absolutely different from well-known Victorinox scales. Collectors and enthusiasts called such shape “Dogbone“.
As SAKWiki said:

The unique shape of this knife was apparently developed for those unable to open a standard pocket knife with their finger nails. This shape allows the tools to be pinched an pulled open.

Only two models were developed with such scales:
– predecessor of Companion / Classic – also known as Duchess;
– predecessor of Princess / Escort (with Alox and stainless steel scales)

Unfortunately, my knife is in a very poor condition, so I have to find another one. If you have such knife (or any other with Dogbone scales) please don’t hesitate to contact me. 

Update from 2017-07-18 – I got it!!!
