Amazon offers the Kershaw G10 Tactical Speed Bump Folding Stud Lock Knife, model no. 1595G10, for $27.31. Add two to your cart for $54.62; at final checkout, they drop to $44.62. With free shipping, that's $22.31 per knife and $7 under the lowest total price we could find for a pair of similar knives elsewhere, although we saw a pair of these knives for $4 less last month. Each knife features a 3-5/8" blade and pocket clip.

They will not arrive in time for Christmas.

Update: The price has increased slightly to $27.89, making the cost for two $45.78.
