I'm glad to see that there are other folks finding it difficult to navigate the "which jig to use" question. I bought the T4 after much research. I read the manual that comes with the machine and am a little more confused than before. I carve with a mallet to start and finish with micro chisels. My largest tools are 35mm at this point, some bent, some spoon, a couple skews of different sizes, intermediate size tools, some palm tools, and some micro carving tools. I bought an SVD-186 jig to start and, after reading the manual, wonder whether I need the SVS 50, the SVS 32, and the TTS 100 to keep everything where it ought to be. I called my woodworking supplier (knowledgable and 25 years of history with me) for advice and they told me to freehand it. All these tools are a big investment and worthless when not sharp. I was hoping for an accurate, repeatable way to sharpen these tools. Has anybody had experience sharpening the whole range of carving tools?
