I'm a sucker for marking gauges, mostly because it is hard to find one that works. Here is a family portrait of the ones I have near the work bench, probably another dozen or so stuck in nooks back in the tool room. I know....I'm a sick puppy with a major tool jones.
The ones I use the most are the first three on the left. What started this post is I just ordered three more of the one on the far left from Tools from Japan. It is not perfect, I guess I will have to make a shop made one to find the perfect marking gauge but it comes the closest to being right of any of the gauges I own. BTW, the Hamilton gauge in Osage Orange next to the Japanese screw locking gauge comes very close, for me it;s only down sides are the marking knife is very hard to sharpen because of its small size and shape and I can buy almost a half dozen of the Japanese oak gauges for the price of one Hamilton.
