Review on 📏 Precision Woodworking Micro-Adjustable iGaging Wheel Marking Gauge with 1/32" & 1 mm Scale by David Pirlet

This review is for the iGaging Micro-Adjust Marking Gauge. This sensor is well made. The fence (the round brass part that you lean against the side of the workpiece during use), the fine adjustment part, and the beam (the steel rod that the fence slides on) are well machined and polished. The lasered markings on the bar could be a bit deeper, but are more than adequate for the intended purpose. These marks are surprisingly accurate (I didn't expect that from a budget mark sensor). The micro adjustment turned out to be more useful than I initially expected. The ability to turn the knurled sleeve to quickly set the exact depth is very nice. Another review here on Revain mentions that the cutter (the little wheel at the end of the beam) is blunt. In my example, the cutter is sharp enough out of the box to easily cut through softwood. It's a little tiring on hard wood, but it was easy to sharpen. IMHO the ability to sharpen cutting tools is an essential part of a carpenter's skill set, whether it's a ripping knife, a chisel, or a cutter on a tracing template. It took me about 20 minutes on a 2000 grit stone and then 5 minutes on a 6000 grit stone to get the sharpness I wanted to leave deep, crisp lines on hardwood. The cutter appears to be made from decent quality steel that is hard enough to retain its sharpness. Knowing what I know now, I would start the sharpening process on a 1000 grit diamond stone, that would probably cut at least half the time I spend with whetstones. While durability remains to be seen, overall this is a well made scriber at a reasonable price and comes highly recommended. PS: There are video clips on Youtube showing how to sharpen cutting discs. Instead of pressing my fingers against the knife, I wrapped a wide rubber band lengthwise around the wooden peg; and then attach the rubber band to the needle with painter's tape and then use the rubber banded end of the needle instead of a fingertip to press the disc cutter against the rod. This technique greatly simplified and accelerated the process of sharpening the circular knife.
