You know you want one.

Finally bit the bullet and picked one of these up. Really does live up to all of the hype. Amazing knife for the money. Fit and finish are awesome.

just what I was looking for

Got this to keep in my AR pistol case, seams well built and for a good price

Grip is just a touch too short for standard Large size hands but it will work just fine. I like this knife and blade shape.

This is my first Harpoon Tactical fixed blade. I like it a lot despite a slightly short grip length. My hands are not XL size. I installed KA_BAR Tan Micarta scales which look and feel MUCH better than the OEM plastic scales. My Comments • This is a Medium/Large size, Fixed Blade - Tactical Knife. It feels very stiff and strong in the hand. Blade stock is typically thick at 1.625”( 41.3 mm) for this size knife and handle. • The knife and sheath combination is lightweight at only 10.5 ounces. Great for hiking. • 3/4 High, Sabre Flat Grind blade is strong behind the tip for piercing. Tip is on handle centerline. • The handle scales are considered Full Length but are just long enough to get a very slightly crowded full grip with bare, size Large hands. It is only a slightly cramped grip. Gloved hands will certainly crowd the grip length space. These Coke bottle profile contoured G10 grips are hand filling. This somewhat abbreviated grip length is the same feel as the Ruike Jager. • Handle tang edges are flush with the scales which provides a comfortable rounded handle feel. I can’t feel the tang and there are no hot spots. • No ‘Pinch Grip’ bevels on the front of the scales but they are rounded. • Knife does not rattle in the sheath with the OEM Ultramid polymer scales but it does slightly with the KA-BAR Micarta scales. • The front handle screw needed to be shortened one thread to avoid contacting my hand when the Micarta scales are installed. • The blade spine has a wide width, full length false edge swage along the entire edge of the Harpoon. • Large thumb jimping on blade spine at ricasso is short and somewhat slick feeling. Could be more grippy. • Flat, slightly protruding and angled handle pommel tang for smashing tasks. • The non-adjustable sheath retention provides a secure grip on the knife but it does rattle slightly. • Five minutes on a strop produced a Razor Sharp edge. • This could be a good all-purpose hiking knife due to its light weight.
