I tried the electric knife. I don't think our knife had the right kind of blade.  I stayed with my filet knife.
  If you want to scale those fish, try using a spoon.  my dad had a fish scaler with two rows of saw like teeth. it worked great. 
He used to go fishing and bring a pail of small perch and gills. size meant nothing to him, since it was my brother's and I who had to clean them.
He also worked building tunnels under the city for storm sewer pipes. a man can stand upright in these pipes. they used 6x8" hard wood ties to shore up the walls and ceiling.
he would bring hole a trunk full of cut-off ends every night for my brother and I to split .. all we had was a single bit, and a double bit axes. we were only about 10 years old when we started that chore.. We got really good at reading the grain in those gnarly chunks.
We 3 boys had the job of mowing the grass.
we lived on 3 city lots and it was on a side hill. my two younger brothers pulled on the rope in front of the mower, and I pushed. No gas mower back then, . Oh wait !! as soon as all of us grew up and left, guess what pa bought ..
 yeppers, a self propelled whirley bird.. 
I don't think we ever completely did the whole lawn at one time. we preferred the prairie look. LOL
