Possibly Walter Trickett, early 20th century......

Maybe Edwin Blyde & Co. But I believe both Trickett and Blyde used similar spur marks.



From the Edwin Blyde website-

Paging Jack Black .
If anyone will know, I believe Jack will.

The mark looks like a catapult/slingshot, to me.

Blyde & Co and Trickett were related, eventually the Trickett family ran Blyde in the early parts of the 20th century. Walter Trickett used the spur mark starting in 1912, the name is apparently still active. The knife doesn't look 100+ years old.
