I met 23,200 hits for this term and 427 hits for "鬼刀 + slash" See: http://www.kenco.com/SLASHBLADE.html etc.

Here is a website that uses the term “cutter blades” for a “solid waste crusher.”
http://www.freepatentsonline.com/4165043.html
In the conventional solid waste crushers, as diagrammatically illustrated in FIG. 1, a pair of parallel shafts 13, 13' arranged to rotate in the opposite directions to each other are provided in a casing 12 having a hopper-like feed port 11, and cutter blades 14, 14' are mounted on the respective shafts such that said cutter blades 14, 14' contact each other partly at their sides so as to perform crushing of the waste material by shearing force.

The cutter blade 3 is divided circumferentially into several segments (three segments 3a, 3b and 3c being shown in this embodiment) each of which is detachably fixed to the holder member 4 by means of bolts 5. The flange portion 7 has on its front side a face vertical to the shaft and a stepped portion for mounting the cutter blade 3 while the rear side of the flange portion is tapered to terminate into integral boss portion 8 of cutter blade 3.


Here is an article from Popular Science which describes a “garbage crusher” and its 5 cutter blades. This invention has “5 cutter blades that don’t spin, but oscillate to crush waste passing through.”

you can use an Allen Wrench under the garbage disposal to turn the cutter blade…or maybe you have the original key that comes with the disposer…you can put your hand in the hole and pull the peels out…there is also a Reset button on the bottom and you can check you see it you need to push the button to reset it.

Here is a product for crushing a variety of materials: bottles, nylon, plastic products, etc. but it has “cutter blades” mounted back to back for a large cutting force.

The shape of the knief-axis is eight character about one's bith. It has a large smashing force for hollow thin-walled plastic products. The installment model of the cutter blade is back to back. So it has a large cutting force.
Sphere of application: It has a good crushing effort for various hollow thin-walled bottles,thin film,woven bags,nylon and other plastic products.Automatic feeding device and automatic delivery filling system can be additionally mouted, which make the production efficiency high

Another word I encounter often on the topic of garbage crushing devices (as a variation on "cutter blades") is "cutting blades."

Also, if you want to use the 鬼 as an adjective, since 鬼 means "sharp" [Source: Nelson's Japanese Character Dictionary], the term "sharp cutter blades" can be used.
