My wife wanted to get me a multi-tool for Christmas, so this morning we went looking at them and I decided on a Makita, (520?), as I already have a couple of LXT batteries and charging stations. Then, as we were walking to the checkout she asked what was I going to build with my new 'toy.
And when I thought about it, I realised I couldn't think of anything specific I would use it for. Got our own modern bungalow, (5 years old and built to a high standard), so can't see anything needing a multi-tool in the near future. In my garage I've got all manner of tools, panel, tenon, dovetail, hacksaw, corded reciprocating, hand-held circular, bench mounted circular, plunge & track saws etc. various other tools(sets), such as routers, drills, (corded & battery), spanners, screwdrivers, chisels, hammers, mallets, various plumbing tools, hand planes, electric hand planes, planer/thicknesser, sanders, (various types), and all manner of other tools. I simply could not envisage anything I would need a multi-tool for that I couldn't do with any of the tools I already have.
So in the end I went for a Makita battery reciprocating saw, for use down the bottom of the garden. I have the LXT battery pack so save some money. My other recip saw is mains powered so save dragging out my extension leads.
