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...
So, I was on reddit talking about my favorite hammer and someone asked how I attached the new handle. I figured I might as well show some pics of it. It's basically a wedged mortise and tenon. I didn't even use glue. It hasn't budged even though I wail on stuff with it on a regular basis.
Here's the original handle for comparison.
This is a little 4 ounce hammer that I bought for $1.50 at my local Daiso. Daiso is like a Japanese dollar store where everything is a buck fifty. I changed out the dinky little handle for a fat piece of iron bamboo. It now hits like a 16 ounce carpenter's hammer with a fraction of the effort. I learned that just changing the handle has a dramatic effect on performance.
