I've been using locking pins with a locking mechanism at the end for years. They were very inconvenient to use, there was never enough room to use the knuckle wrench. But this locking mechanism faces forward. Hooray, no more bruising! And maybe it's just me, but I love the look of these high quality stainless steel parts, they exude quality.
