In the early days of building your workshop it's important to invest in tools with multiple functions so as to get the most bang for you buck. Now normally I'd think a blowtorch doesn't exactly fit that criteria, although since reading this I'm beginning to rethink that...Need to loosen some bolts? Blowtorch.
Need to cook a steak? Blowtorch.
Hell, need to kill some weeds? Blowtorch (it's more efficient than you'd think).
