Brownie points, who needs them, but if you are a little low on credits and you MIG weld with throw away gas cylinders, cut a tapered slice out of an empty bottle (Usual cautions apply) and knock up one or two of these garden tools. They are ideal for digging dandelions out of the lawn, planting seedlings etc etc. Use a thin cutting disc in the angle grinder to cut the bottle and don’t worry about a few wood shavings on your precious ML7 that you have meticulously painted when you make the handle.
