How to Change the Blade in the OLFA MXP-L Ratchet Knife
The MXP-L uses OLFA's tool-free TAB blade change: press the blade release, slide the old 18mm heavy-duty blade out of the channel, insert a fresh OLFA LBB or compatible 18mm snap-off blade, and retract the ratchet wheel to lock. No screwdriver required — a blade swap takes seconds on the job site.
Blade Depth Adjustment
The brass ratchet wheel advances the blade in secure click increments, letting you set exact blade depth for scoring drywall, cutting rubber, or slicing thick material. Ratchet-locking holds the blade firmly under pressure where friction locks slip.
What Blades Fit the OLFA MXP-L
The MXP-L accepts all standard OLFA 18mm heavy-duty snap-off blades, including the ultra-sharp black snap blade (preloaded) and OLFA LBB blades. Buy OLFA 18mm refill packs to keep this knife cutting all season.
Price Value and Deal Value

Comparison: MXP-L vs Standard Utility Knives
Plastic-body knives flex under load; the MXP-L's die-cast aluminum body and stainless support channel stay rigid through repeated heavy cuts. If you only need light-duty precision, see OLFA's 9mm A-1 or SAC-1 — but for construction and MRO, the MXP-L is the differentiator.
