10 cm Petzl Laser Speed $35
13,17,21 cm Petzl Laser Speed Light $40

They’ve seen moderate use over a few seasons.  A few have had a little bit of sharpening done with the Petzl screw sharpener.  A couple could use a touch up sharpening (which I’d do but can’t find the sharpener right now)

Buyer pays USPS shipping. Or local pickup in Portland or Redmond Oregon.

4 screw minimum purchase.

I’ll give ya 10% off and cover shipping (to CONUS) if you buy the whole lot.  That works out to a total of $595 or $35 per screw.
