dristo72,
I would recommend the
Howard heavy duty slasher as they stand up to rough work. We have used them in the past and found that even if you hit bricks or rocks etc they don't fall apart.
The
Jarrett brand seem to be not as well built and the
Superior brand is another good brand that we have used in the past.
Hopefully this information will help, just click on the names for their websites to get more information on what they make.
