The OLFA BN-AL 18mm Auto-Lock Basic Utility Knife is a discontinued OLFA model available in limited stock at Cutter's Bench. Buy it online for $9.49 while it lasts — this is the auto-lock heavy-duty knife for drywall, construction, and all-day cutting.
Yes, the BN-AL has been retired by OLFA. Once current stock sells out, it will not return. The closest current alternatives are the OLFA L-1 ($10.00) with ratchet lock or the L-2 ($10.00) with rubber inset grip — both use the same 18mm heavy-duty blades.
The easy slide-lock lets you extend the blade quickly one-handed and locks it firmly — ideal for fast, repeated drywall and packaging cuts.
The stainless-steel channel fully backs the 18mm snap blade, giving rigid support for scoring and cutting drywall, insulation, and sheet materials.
At $9.49, this is the lowest-priced 18mm heavy-duty OLFA knife on our storefront. Add coupon BENCH10 for an extra 10% off, and pair with an 18mm blade multipack to reach the $45 free-shipping threshold before this retired model disappears.

The slide auto-lock means the blade stays put no matter how hard I push. Used it on carpet padding and cardboard all week with zero slip. Comfortable in hand and easy to snap the blade segments. Great buy.
No frills, just a well-made knife. The stainless backing feels sturdy and the lock engages smoothly. Good value.
Sharp, sturdy, locks tight. Exactly what I needed.
I'm a retiree who does foam board models and opens far too many Amazon boxes. This knife is light enough for my arthritic hands, and the auto-lock gives me confidence it won't slip. The blade is razor sharp out of the package. My son borrowed it and now I need to order another.
Cuts cleanly and the auto-lock works as advertised. My only issue is the slider takes two hands to retract when wearing thick gloves. For everyday use it's great though.
Replaced a cheap hardware store knife that kept slipping. The auto-lock on this one is night and day — blade stays exactly where I set it. Feels premium for the price.
The slide action was extremely stiff when new and took a week of use to loosen up. Works fine now, but that initial friction was frustrating and I nearly returned it.
Using it for cutting insulation and shrink wrap at work. The grip is decent and the blade is easy to snap. A lanyard hole would make it five stars.
Third OLFA knife I've owned and the quality is consistent. The auto-lock is smoother than the ratchet on my older model. Highly recommend.
