I bought this mallet years ago for 3 bucks (plus a 20 percent coupon) at harbor freight.
It came with this crappy, small rubber handle that, not only looked cheap, but had terrible ergonomics.
I cut it off, drilled out a piece of iron bamboo and attached the iron bamboo with regular wood glue as a new handle.
Wow! Completely different look, feel and performance! I'm completely happy with it now and use it daily!
I highly recommend picking one up and modifying the handle. For just a few dollars, you'll have an effective and efficient tool that will serve you for years.
