Pro utility knife for trade cutting

The OLFA SL-1 is a 6 in utility knife built for professional cutting of carpet, drywall and wallcovering. Its heavy-duty ABS handle resists impact on site and the bright yellow colour keeps the tool visible in busy work areas.

Sustained cutting with one-touch lock

The slide-lock mechanism secures the blade with a single action so it will not shift during long scoring or trimming runs. High-carbon steel holds an edge through repeated passes on abrasive materials without frequent blade changes.

3/4 in blade thickness for deep cuts

The blade measures 3/4 in thick, giving the reach needed to penetrate dense carpet backing or plasterboard in a single stroke. Thinner knives cannot achieve this depth without multiple passes.

Questions about this item

How does the ABS high-impact plastic handle feel after a full day of cutting drywall?

The heavy-duty ABS handle resists heat buildup and stays comfortable during extended use, while the yellow colour keeps it visible on a busy job site.

What blades must I already own for the one-touch slide lock to work?

The knife accepts standard OLFA high-carbon steel utility blades; the slide lock engages any blade of that thickness without extra tools.

Will the 3/4 in thick blade holder fit the older OLFA snap-off blades I keep in my toolbox?

No — the SL-1 is designed for fixed utility blades only; snap-off segments are too thin for the slide-lock mechanism.
