This unique dagger was hand forged from an old steel open end collet wrench. Hardened and sharpened. Very sharp, very durable, and should last a lifetime. 
 
This vintage machinist's collet wrench has the following manufacturer engraving:
Jacobs KA20B
 
Artisan handcrafted in a genuine grassroots metalworking shop. We have an intentional design with our wrench blades...performance and quality of a precision-made instrument but with the appearance that the mechanic went over to the shop bench and quickly made it out of necessity. Something you'd expect to see out in the wild...
 
This would make a great gift for mechanics or just overall tool lovers. This is a great conversation piece as well, leave it laying on a table or desk and you'll find that many hands and eyes gravitate to it right away.
 
Approximate overall length = 5.5"
