I've some hand tools bought for me for Christmas I've rarely, if ever, used. Mostly "trick" tools that my wife thought looked handy/interesting and either the "tool guy" at the store or some other shoppers in a tool crib told her were great. There are others like those that
have turned out handy.
Tools
I've acquired but never used? First there's the micro-plunge router I bought when I thought I'd get into fine woodworking. It's been sitting in the box, after being played with a bit, for probably twenty years. Good news, though: It'll be real handy for making the dados I need to make for an upcoming project. (I've already done some experimental practice joints with it.)
Bought around the same time: A Delta Sharpening Center. I was doing
a lot of tool sharpening at the time. Unfortunately, not long after acquiring it I figured out fine woodworking in an uninsulated, unheated garage was a non-starter and I didn't have the patience for the hobby, anyway. So it's sat unused ever since. (Along with my Japanese water stones and a bunch of other sharpening tools.) But I'm thinking I may get back into sharpening, again. We'll see.
Recently acquired, used: A Porter Cable biscuit cutter. Acquired a couple months ago for the same project as above, because I
thought I'd use it. We'll see.
There's a farm jack out in the shed that I
thought I was going to use to correct a foundation problem with the shed in which it's sitting. Yeah... no. Wrong tool. Way wrong. This is one of those "Now that I have it, I hate to get rid of it, because I may need it some day" tools. I think it's going into the next garage sale, though.
A
seriously heavy-duty, fiberglass articulating ladder. Thing weighs a ton. I've replaced most of its functionality with a newer aluminium articulating ladder. That thing
definitely needs a new home.
Other than those: I've got a lot of tools of all kinds. I guess I'm a tool junkie

. But, other than the list above, I use them all. Some only rarely, but, when I need one of those tools I'm sure glad I have it! The right tool for the job can turn a PITA job into, if not a joy, at least not as much a PITA
