Looking for the ultimate lightweight rear-handle climbing saw, or just a ripping little firewood saw? 309 Machine's CNC-ported HP261C packs a lot of punch in a little package.

HP stands for High Performance, and that's what we're all about. We work to get the most power out of every saw while keeping durability and reliability front and center.

  • Intake port timed
  • Upper and lower transfers enlarged and aimed
  • Squish band cut for a tighter combustion chamber
  • Base cut for increased compression
