The Slammer is a multi-tool combining
a sledgehammer impacting on a digging
bar and an axe head.
It uses the downward force of the
inner bar to slam the cutting blade
through tough ground, soil, roots,
wood and concrete.
WHAT IT IS AND HOW IT WORKS.
A NOTE FROM INVENTOR, TJ IRVIN
“Congratulations on purchasing a Slammer tool.
I didn't initially make the Slammer to sell commercially. I just wanted a simple,
indestructible, multi-use tool for myself for tough, labour-intensive jobs.
I used to use a crowbar (digging bar), mattock/grubber, axe and spade when
dealing with hard ground, roots, rocks, concrete and well-compacted soil types
(clay, sedimentary, conglomerates). However, once I started using the Slammer
I found not only did it take less time to complete a task, it used a completely
dierent set of muscles that did not hurt my back. The key to this was to grip the
bar with my hands but use my legs to get my body to move the bar up and down,
rather than my arms. The other big feature was the blade design. Once the tool
was driven into an ugly patch, to get it out was a lot of work. But by rocking the
5-sided blade from side-to-side it “walks its way out”.
Clients, co-workers and friends saw my Slammer and asked if I could make
one for them. Then things just escalated through word of mouth and the
Slammer Ltd was born.
The slide-hammer concept has been around for a long time but the design
and materials used for the Slammer has been a 23-year evolution of countless
prototypes to make it as sturdy and robust as the one you see today.
I filed a PCT patent 583181 in 2008 and took the Slammer to agricultural,
horticultural and trade shows where it has been well-received by a very diverse
range of customers.
This manual aims to provide you with a few tips and uses that I have learned
along my Slammer journey. Other techniques have been shown to me by
customers who have provided comments and feedback. Please get in touch to
let us know what you think of the Slammer and what you use it for.
HAPPY SLAMMIN'!
