    I’m a round guy since they fit into my cushion back cutter and my knife and I don’t have to have both blades. Some guys I know hate round blades.

    I don't have a reason but I will die defending round blades, probably in a knife fight with a fellow with square blades...

    Strange to me how anyone likes round. To me it gives the impression that it’s dull already. I like the point to get into product cutting.

    I really liked the square corners for when I had to back trim softbac or berber. Sharp as all get out. My newer 301 cutter takes square corner blades, the older one didn’t. I’m older now so everything gets cut with either a utility blade or a hook blade. I just don’t have a need for that level of sharpness anymore.

    Round for me. It's what I come up using & feel the most comfortable with.

    Those damn things are sharp as all hell. Add a point on them & their lethal.

    Everytime I nick myself with a round blade, I realize it would have been an 1/8 inch deeper had it been square.

    Round for me. The sq. always seemed to get dull at the point faster. Could just be me.

    Originally the square were called slitter blades. To me as soon as the point dulls the blade is no good. I have take my top cutter when cutting carpet on concrete and have worn the round blde almost to the slot and it kept cutting.

    :old:

    Square. Same reasons Mike Antonetti stated.
    Usually buy them from a distributor, but sometimes need them quick & have to purchase them at a box store.
    They both stock the Personna's, Lowe's/round & HD/square. Strange.

    Yes, I tried the square ones and they dull too quickly and do not fit in the top cutter. Worked with a guy who showed me using the square carpet blades on radial (rubber) tile. Worked bitchin' but I can't buy a box just for that.

    Do you sharpen them on a stone?

    We handle Personna and FloorDot blades and it's about 99% round to 1% square with regards to our sales figures. Just thought I'd share that for what it's worth.

    We have one semi-retired mechanic in his 70's who still does everything with a ward knife and different ward blades depending on the product . He swears by them.

    those are the same blades for the airway knife I’ve used one but didn’t see the point in special blades for a special knife that cost so much.

    In Cleveland and in Pittsburgh it’s more like 50/50 square vs round.
