I had the TSC Chinese kinetic spliter for a while my split fire with a 4 way is faster and safer.
The kinnetic likes to throw pieces back at the opperator if there are knots in the wood. They ride up the wedge and get propelled back.
It took a minimum of 3 splits to quarter a log with the kinetic whereas the splitfire does it in one
I also like the hydraulic log lift it makes a great table for smaller stuff
How heavy were the flywheels?
