I have one of these knives that is over 5 years old. One of the yellow clip parts has broken off since, but the knife is still functional. Two more of these knives I purchased just over a year ago. One of them, after being dropped from 1m, broke when the yellow plastic clip things snapped off. That knife had to be discarded. The third knife is still.good.

    Great brand. Great knife. But use bigger one for boxes. Besides with an tabletop paper cutter i don't find I need it for anything rn. Although if I got back into charcoal drawing, especially reductive work, I would use this for sharpening mechanical eraser sticks.

    I have been using the same Olfa 9mm for over 20 years. Just bought 2 of these knives for other work stations in our business and it's nice to see Olfa's quality still remains the same. Tough, sturdy tools and I'll probably see another 20+ years out of these new ones too.

    I bought the bigger version as well .. nothing but quality here .. they are not cheap , but it's the best one i've ever used. Fully metal lined to support the blade, ratchet mechanism works flawlessly and unlike cheaper version , the blade stays exactly in the setting you desired , you can apply pressure and the blade stays firmly in place and cuts like butter. you get what you pay for, and it's worth every penny!
