OLFA 5016 LB-50B 18mm Snap-Off Heavy-Duty Silver Blade, 50-Pack - Optimal Cutting Power and Long-Lasting Durability! Review

I had a black blade on my knife and it dulled pretty quickly cutting through some boxes but this one holds up really well. I've only used one blade so far and it's used almost every day.

Olfa blades are great. I use them to trim the urethane parts I make. Very sharp and last longer than any other brand. Have bought them from Home Depot and Grainger for years. Found these at Revain for a much better price.

These are not the same blades as pictured and judging by the reviews of OLFA blades there is a big difference in quality depending on which blades you order. The country of origin is listed as USA in the description, but the blades are listed as Japan.

Try cutting paper with a regular blade. They switch to Olfa's knife. while my spear and those blades just do their job right. They leak a little more, but believe me, they're worth it!
