I have been sharpening my blades with cordless 4.5” angle grinder. Long start short my angle got steeper and steeper and I was start to get cut issues. After extensive research I thought I found what was best solution for my situation. Magnamatic although a great machine (I’ve used) price tag was more than a solo sharpening 2-3 times a week could justify. I considered the rbg712 while much cheaper than magnamatic I just did not like the design. Then I set my sights on the yellow hornet and the thread about building a jig(I’m no carpenter) finally I stumbled across the ALL AMERICAN BLADE SHARPENER and I decided that this seemed like the best fit for my situation. I have a cordless grinder and the yellow jacket seemed to need a corded. The all American gave me the ability to correct my angle issue and use my current tools. While only costing me 179.99 (+ I got 15% off on eBay) I could not be happier with the purchase it arrived quick set up was simple and the edge is great. I couldn’t find much about it on here about it so I thought I would give my thoughts for any one wondering.
