It's the yellow "Central Forge" brand cutter & 3 blades in the yellow & red package (Item # 95378) for $3.99. The replacement blades must be the same brand, & they come in packs of two blades for $1.49. I found the cutter & the hook for the blades just below the cutter, in the same aisle, on the opposite side of the aisle, as the tape measures and hand saws, etc.
