The Tanto Groove is the first blade I bought . It is definately my most aggressive knife. The grooves are more subdued than you think and cleaning is easy. The Tanto Groove has an ideal blade for thrusting. If I was in an emergency defense situation the Tanto Groove would be the knife I would want to have with me. I would like some thumb studs as well. The knife is also on the heavy side but is all metal and has G10 Overlays. It feels solid as a rock in hand. The flipper is good but you need some wrist movement to get it out quick. It is a different kind of knife than my others, Manix 2, Blur, Mini Grip. Less of a EDC more of a Tactical, defense knife. The Sandvic is really hard to sharpen for me and the Tanto blade dosen't help. However the tanto tip is great for cutting paper and opening mail etc. I love this knife and love the fact that it is not like most edc folders.
