You can never have too many clamps in the shop, and specialized ones are better still. Take the cabinet claw, a clamp that makes it easy to align the faces of two pieces of wood — it allows you to pre-drill for assembly screws using a drill guide built right into the clamp.
The cabinet claw can hold two stiles with widths of 1-1/2″ to 2″ each, for a total width of 4”, and a thickness of 1-1/2″ each. The pre-drill hole, which is located on one of the clamp arms, allows you to drill a guided hole and drive a fastener through each piece, for an accurate alignment and tight fit.
We can see where this would be handy for cabinetry and furniture building — we just wish it came in a bigger size. But any help keeping seams tight is better than nothing.
Street pricing starts around $55.
