PRO Picks: OLFA Utility Knife Blades
Faster swap-outs, longer reach, and serrated blades for cutting fibrous materials (like insulation)
At the 2018 JLC Live show, Bill Robinson pointed out a tool that he likes to use—and talk about: snap blades from OLFA.
In the moisture management field, Bill cuts a lot of sheet goods that can dull a utility knife pretty quickly, house wraps, flexible flashings, rigid insulation, etc.
Bill uses a snap blade knife for several reasons:
- Serrated blades make cutting rigid insulation easier.
- Extendable blades can gain you a couple of inches when reaching up to cut house wrap.
- When the blade gets dull, you can break off the last segment, effectively getting a new sharp blade without the time involved with unscrewing a traditional utility knife to swap out the blade.
