It's like a hammerdrill
except it's a knife. Alternatively, a knife crossed with a small jackhammer.
The other day I was cutting some slices from a block of cheese, as I have many
times before, and once again painfully noticed the quite large amount of force
necessary to push the knife through the cheese.
To solve this, I propose a knife with a mechanism built into the handle to apply
blows through the blade, in the cutting direction. (To achieve this from
the handle, the blows must have a rotational component, I think.) You would just
press down lightly, and the mechanism would either use an electric motor to
hammer the knife through the thing to be cut, or would operate like an
automatic center punch (but repeating) to harvest energy from your continuous
light pushing and concentrate it into short sharp blows.
This would be useful for cutting many things other than cheese. With a
sufficiently strong and hard blade (not necessarily a contradictionsee composite
metal swords), it should be possible to cut metals, which would be useful for
harvesting components from appliances found dumpster diving, for example.
An advanced version could have a sagitally split blade similar to that of an
electric carving knife. One side of the blade would hammer down at a time,
cutting a little further, while the other would remain in place, stuck to one side
of the kerf either through friction or using barbs, as an anchor for the blow
and/or energy harvesting.
(?) Existing chisels for jackhammers
You do realize that the thinner the blade, the less force you can apply before its shape warps? [Vernon, Sep 28 2016]

||Something similar to a slide hammer with a blade ?
||Or an axe - a thing who's caveman-name is synonymous with "hammer knife" - probably.
||A squirt or two of spray cooking oil on the knife
does the trick, I find.
||A chisel with a handle that slides toward the cutting edge, if heavy enough, would act like a slide hammer. The chisel would act normally but in needed cases, tapped with the sliding handle.
||I don't think it would be good for cheese though, a bit sticky unless you like cheese dried out. A cheese chisel then, might be appropriate.
||How about a cheese chainsaw?
||I remember what I thought was a Monty Python sketch showing one of those nordic handheld cheese slicer tools one draws across the cheese. The next scene is putatively the Norwegians using this device in a chaotic frenzy, hacking at the cheeses, prying bits off which go flying etc. But unlike everything else Python has done I cannot find that on Youtube to link it. Can I have dreamed it?
