That is a very "doable" feat with a Rapala HD electric and a set of Berkely slim blades.
Regarding the slim blades, one must alter them a litle with a dremel to get them to insert/remove properly from the HD Rapala. Matter of fact, anything other than the blades that come with the HD must be modified slightly. The HD has a slightly different retainer profile within the housing. It's a 2min fix on a set of blades with a dremel and the die grinding bit.
Still not going to use an electric knife. SO THERE!!!!!!!!!
