    Great product!

    I bought this to mount to my rifle as a bayonet, very cool addition and it looks and works great! The customer service was also very helpful as well, I would definitely recommend buying from this seller.

    Fits and works nicely

    I love the fit and look but I was a little suprised to find the sides are not sharpend at all

    Hey Brian,
    If you would like I am happy to exchange the UPK-D4 Eclipse AL for a UPK-D4T Eclipse Talon, this evolution was created specifically to address the desire for improved capabilities. The Talon adds a hardened HRC:60 Stainless steel double-edged razor tip to the lightweight AL version. Just reach out and I will credit the return towards a sharpened model. I also offer a Full stainless double-edged blade in the UPK-D4 Eclipse SS-AL.
    Thank you for your support,
    John Risch UPKnife
