Amazon offers the Kershaw G10 Tactical Speed Bump Folding Stud Lock Knife, model no. 1595G10, for $26.60. Plus, Prime members qualify for free shipping. (Non-members can spend $35 to qualify for free shipping; otherwise, it adds $6.72.) That's $13 under the lowest total price we could find for a similar knife elsewhere. (For further comparison, we saw two knives for $46 in December.) Features include a 3-5/8" stainless steel blade, stud lock, assisted opening system, and pocket clip.
