Sears offers the Craftsman 2.25" Blade Folding Lock Back Utility Knife in Red, model no. 700587, or Black, model no. 700583, for $3.99. Plus, Shop Your Way Rewards Members will earn around $4 in SYWR Points. (The points can be redeemed from November 30 to December 6. Not a member? It's free to join.) With free shipping, and assuming you'll use the credit, that's essentially free, a savings of $6, and the lowest price we could find. It features a rust-resistant stainless steel blade and aluminum handle.

Of note, Shop Your Way Rewards members will earn a Sears credit with this purchase and may be eligible for additional credits and discounts. There is a limit of $50 in points per member for items in the 100% back in points promotion.

Update: It's now available for in-store pickup only.
