    SPARTAN-HARSEY FIGHTER

    Published by David Latona on Oct 20th 2025

    The service, shipment and blade are 100% fantastic. Only reason I downgraded the review is because try as I may I can’t get a left-handed sheath for this knife…very annoying

    My Go To

    Published by Garrett on Jul 21st 2025

    This is a great knife. The blade length is in that sweet spot, the grip is oh so comfortable, and I love the sheath with thumb release. This is the knife I train with simply because it is a cheaper steal than the pro grade blades and if this one gets destroyed somehow it won't break the bank. The blade is really thick at the spine making this blade a lot heavier duty than other knife brands out there. I would like to make one suggestion. Would there be any way to get that beautiful thumb release integrated into the pro grade kydex sheaths? There just really is not much in the way of being able to improve this knife unless it was upgraded with a Magnacut or s45vn steel......but then it would probably be out of my price range.

    Nice Blade

    Published by Edward Shattuck on Oct 15th 2024

    I wasn't sure what to expect when I ordered this blade. I usually buy the blades that made of Magnacut. I was greatly surprised. It has great balance and is weighty in the hand. Also I was pleasantly surprised that the handle was quite substantial. Overall this is a great blade that will give years of service.

    Quite Surprised

    Published by Ed on Oct 12th 2024

    I was very surprised first at the left of this blade. It is nuce and heavy in the hand and has great balance. If it's a Harsey blade then it's a sure thing that you'll have a high quality blade.

    Near perfection

    Published by Chris Welch on Dec 19th 2023

    This is one of the best knives I’ve ever purchased. Being well balanced, the weight of the handle feels solid, and I described as a true tactical tool. The handle shape makes transition from saber to ice pick easy and the up flare at the handle end with the guard gives confidence in aggressive use. The sheath with the release button works with the perfect pressure for release, giving some security with movement but not being a hindrance to quick use. I would have liked to have this on deployment. Spartan blades made a quick adjustment to my order for engraving, even though I made the mistake of emailing the details late. The quality of work speaks to the precision and dedication of an operator’s mindset. The craftsmen should be proud.
