Had this on Tool Talk and figure it might be a bulb planting tool. However, sure seems overkill on construction. The blade is just over 1/8" thick, three stainless rivets in the handle and it is of a very hard plastic?. The blade is stainless, sharp on one side and a saw on the other with a sharpened notch at the end (somewhat like a skinning knife). On the back side are inch numbers, 1 through 4. Seems like an expensive item to plant bulbs. Note: it has a Craftsman number Y6 40106 but it doesn't lead to anything at Sears. Watcha think?
