    Love the knife but it doesn’t seem to hold an edge.

    Off the top, product box in bad shape. Found what looks like slight rusting at blade tip. Blemishes to finish, edge. Knife could be a return product repurposed. Purchased with credit card with charge to Lee's innovations. Resell? Unknown

    Sharp out of the box, nice make and quality build Bolo - sheath fits well, handle snap/velcro strap is a tad shorter than usable - needs adjustment but will work with patience.

    One of the machetes I have purchased I have half dozen maybe 9 machetes this thing is a chopping Beast is great and a hand well-balanced could have been a little shopping when it came. But without chopping it I just took it out of the box and went to work extinct work all day without tiring me at all

    OKC sets the standard

    Saw my first OKC knife in Kyrgyzstan while serving in the Air Force and I couldn't believe the quality of the folder. This SP 53 Bolo is no different. From the time you hold it in your hand to put it to work, you realize you've got quite a blade in your hands. Rugged, durable, and quite functional. Beyond impressive!

    Although I have not had a chance to try this knife, I am extremely pleased with it. It looks great and it came with a perfect edge. Amy was a delight to talk to.
