Dear Andrew >Doug mentioned the Laimet, earlier Sasmo, helical/spiral blade. I never did think much of them because it seemed that the increase friction path of the blade lead to loss of efficiency compared with a direct slice and I worry about this with the part rotation of the disc blade as it travels through the wood, however the proof is in the pudding...
>In the past we discussed modified chaff cutters which were hand operated: http://www.bbc.co.uk/ahistoryoftheworld/objects/Ip6tPg0kTH-wrFzK-uWpSw ++++++ There is some merit in the slicer when looking to cut woody things. The guillotine is much more difficult to operate, in my experience. If it bends the material away before slicing, things get even better. You can try it with a pen knife: cutting directly at 90 degrees or slicing into wood at 45. The one at the link above is really advanced when it comes to safety which is good because this sort of machine was responsible for more lost fingers than any other piece of farm equipment. A variation on the same drive mechanism was used to crush sugar cane juice on a cup-at-a-time scale. The blades of course were missing.
