Outstanding holdfast!
I had purchased an import cast holdfast from a local woodworking store which was supposed to work with 3/4 inch dog holes. It held my workpiece about as well as tape would do. Useless! I saw this holdfast on Amazon, placed my order and it arrived from the Land  of Enchantment via USPS. I have been happily chopping dovetails ever since.
