I noticed a few JP bladesmiths using a horizontally positioned "grinding wheel sharpener". Which seems to make more sense than using the usual vertically oriented Machines (e.g. Tomek T4). I know Makita had a 9820-2 ($800 CDN on Amazon.ca)...another company..the Wood Worker ($300) is the name? Had one for chisels but only had angle settings down to 20-degrees...though, if keeping the factory angle isn't important... Love to get some brand/model recommendations. Preferably from people who've used or are still using this kind of sharpening machine. Thanks.
