A well designed jig used for re-grinding both guillotine blades and power planer knives of any length and minimum width of 13mm. Grinds each blade identically so they are never out of balance. This jig allows you to measure exactly how much is to be removed. Tormek T-7 is recommended for this jig.

Good but messyI have had this jig for over a year. It is certainly good quality, and it does its job well. However, it makes a hell of a mess. Dirty water gets everywhere, so it needs to be set up over a big bowl. The other thing which is critical is that the grinding wheel runs true. If it is slightly eccentric, then the results are less satisfactory. It means buying the diamond truing device as well. The other thing to note is that this is not a quick process. It takes a while to set things up properly, and if the planer knives are badly nicked, it can take over an hour of grinding to get them conditioned because the stone cuts slowly even after opening up the stone with a coarse grader. Afterwards the planer knives will still need a bit of hand honing to get them perfect. Overall it is a good jig, but the process is slow and messy.

Excellent tool but needs time to get used toI bought the Lie Nielsen book on sharpening (Taunton Press) and he praised highly the Tormek so I bought the jig. I had trouble getting the edge I needed (30 degrees) despite reading the Tormek booklet. I had the blades professionally reground on a massive and expensive machine. I then took the blade and spent considerable time to setup the Tormek jig (after using the diamond redressing stone) as accurately as I could. Now things work perfectly... and I have reground and honed the blades many times with a 30 degree angle.
