Walmart offers the Whetstone Black & Blue Tactical Rescue Knife, model no. 25-SP606-B, for $5.99. Choose in-store pickup to avoid the $4.97 shipping fee. (Amazon charges the same with free shipping for Prime members, albeit with a three to five week shipping wait.) That's tied with last week's mention and the lowest total price we could find now by $2. It features a 3.25" stainless steel blade, seatbelt cutter, glass breaker, liner lock blade, and belt clip.
