How This $79 "Wrist-Saver" Saved My Sanity in a Joist Jungle
When I was dangling from rafters installing hurricane ties during the Miami rebuild, my hammer slipped for the 17th time. Enter the Bostitch PN100K—a pneumatic beast that sunk 3½" ring shanks into LVL beams upside-down like butter. No more swollen knuckles or rogue nails impaling drywall. For framers, roofers, and deck builders fighting confined spaces, this isn’t a tool—it’s orthopedic armor.

Verdict: Your Tendons Will Send Thank-You Notes
At $79, this palmtop powerhouse eliminates the two worst job-site curses: bouncing nails and busted wrists.

Like my spinal surgeon joked after my last job: "I miss your business—but keep using that thing."
