UPK-M Series

The Ultimate Tool.

Built to Do.

 

 

 

Milled handles in Custom 450 H900 Stainless Steel hardened to HRC 45

The UPK-M1 was the original knife model created by UPKnife to debut the bolt-action system and was limited to 100 pcs though less were released due to high quality standards.  The first 21 were produced without serial numbers, except 0009 which was marked at request, all knives numbered 0022 and up have a serial number marking.

UPK-M2
Current Model
The UPK-M2, is fundamentally built on the M1 and offers optimizations to the design while maintaining the original slim outer dimensions.
To list a few:
  • Additional front handle grooves for improved grip
  • Larger Wider blade with more acute primary bevel angle with no increase in handle dimensions, improves slicing resistance by reducing drag.
  • Shorter bolt-lever action stroke, easier to open by reducing reach required while maintaining the length of sharp edge (witchery used)
  • Improved blade play tolerances through improved blade rail design
  • Hidden hole added behind the lanyard loop, easier debris cleaning and lube access

  • 3 Position Bolt Action OTF Operation
  • 3.25” 440C Heat treated Blade
