When i used to survey with my daddy in law we called the Kaiser blade a
Bush hook. A wicked chopper until you tried to chop a hedge apple tree.
Hedge apple is really an Osage Orange tree. Thats what they used to make
oxen yokes out of.The first hit and your arms feel like 110 voltage just just barely got ya.Another few stings and then you might be into the wood! The blades on the bush hook could bend in half but didnt
hold an edge long. No biggie.. The handle was 48 inches long.!!
Rare back and swing and it was down far enough to see with a survey
instrument. Thats my memories of the Kaiser Blade/ Bush Hook.
