Love the look of a double-edge blade but love the usability of a single-edge or tanto?
Well now you can "have your cake and cut it too", with the Bayonet blade from Microtech Knives.
The best part about a Bayonet blade is it's sharpness on both sides, however your top edge is sharp 3/4 of the blade with a spot for your thumb to rest the other 1/4 of the way.
This OTF Automatic Ultratech features Microtech's 6061-T6 Aluminum Handle with Satin hardware. It's topped off with a Satin Bayonet blade, perfect for any use

    Love the bayo grind. Fit and finish everything expected from microtech. My only concern is that it seems a little sluggish on firing whereas retraction of the blade occurs with a thunderous snap. Maybe just a goofy spring on this one. Could just need to break in a bit.

    Excellent build quality, super sharp blade, and great lock up for an OTF knife. Outstanding service and quick shipping from eKNIVES. A+
