The tool aisle is heavy, oily, and full of things that still work. That is the opportunity and the trap. A Stanley plane with its iron, a Craftsman set that is actually complete, and a marked chisel with a straight edge are worth picking up. A bucket of sprung wrenches, a saw with a kinked blade, and a drill with a cracked battery from a dead platform are weight. This note is how to tell them apart in a few minutes. It belongs with what to flip and with buying used instead of new, because the best tool purchase is often the one you will use.
Hand tools first
Read the stamp. Stanley, a size, USA or a later country, a model on a plane’s toe. A number on a Bailey plane is the maker’s size, not the length in inches. A wrench with a worn-off size is a wrench you should not guess. Count a socket set against the tray. The missing 10mm is the one everyone needs, and it is the one that is missing. A ratchet should click one way and lock the other. If it skips, the listing says it skips, or you do not buy it as a good ratchet.
Surface rust wipes off. Pitting in a jaw or on a plane sole is damage. A wire wheel on a plane’s japanning ruins the finish people use to judge age, and a wire wheel on the sole ruins the surface you need. Do not “restore” a tool in the parking lot. Oil it, photograph the rust, and decide. Griswold is the kitchen version of the same rust lesson. The tool guides cover the plane and the wrench in more detail.
A sewing machine is a tool that pretends to be furniture. Read the model plate. Do not plug in a cloth cord. A stitching portable is a different object from a frozen machine in a ruined cabinet. The cabinet is why people rent a truck for a common Singer. Most of the time the truck is the mistake.
Power tools, cords, and batteries
A corded tool you can plug in, that runs, with brushes that are not a shower of sparks and a cord whose jacket is intact, can be a fair used buy against a new one. Look at the cord. Cracks, tape, and a missing ground pin are a reason to leave it. You are not saving money if the first job is a shock.
Battery platforms go obsolete. A drill with no battery, for a system the maker no longer sells, is a drill-shaped paperweight unless the bare tool is cheap and you already own the batteries. Test it with a battery you trust if the store allows, or price it as untested. “Powers on” is not “holds a charge” and it is not “the clutch works.” Say the test you did.
Blades and bits are consumables. A saw with a dull blade is a saw. Do not pay extra for a rusted bundle of bits. Air tools need a compressor you may not have. Leave them unless you do.
What is worth reselling
Complete hand-tool sets with readable marks, older styles people search, a plane that is complete, a small portable sewing machine that stitches. Those can be listings if the sold comps survive the fee and the postage. Weigh the plane before you promise shipping. Pricing includes that weight.
One common wrench is not a listing. A can of mixed sockets is a can, unless you sort it. Local pickup is the right market for a heavy set and for anything you have not fully tested. Estate sales put an entire garage on tables. The markdown on Sunday does not straighten a kinked saw. It makes a kinked saw cheaper. Cheap and useful are different from cheap and broken.
Measuring tools, edges, and where it was made
A tape that does not lock, a square that is not square, and a level with a bubble you cannot see are not bargains. Check them against something you trust if you can, or price them as untested. Calipers and micrometers need to close on zero. A micrometer that does not is a paperweight with a nice case, and the case is often why it looked expensive on the table. Leave the rusted one unless you know how to lap it and you priced the labor as yours.
Chisels and plane irons are edges. Sight along the back. A belly, a chip out of the corner, or a weld someone used to “fix” a crack is the price. A full-length iron with the maker’s stamp still readable is the object. A shortened iron can still cut. It is not the iron in the catalog photo. Handles crack. A cracked handle on a chisel you will use is a shop job. A cracked handle on a chisel you will mail is a disclosure, because it will crack further in a box.
Country of origin is a search term, not a moral category. USA, and the earlier marks some makers used, are what certain buyers filter for. A later tool made elsewhere can be a perfectly good tool to use, and a poor flip if you bought it at a collector’s price. Read the stamp before you pay the collector price. A worn stamp you “think” says USA is a stamp you did not read. Photograph it in the aisle. If the photo is mud, you do not have the claim.
Where a tool actually sells
Hand tools sell to people who will use them and to people who collect a maker. Those are different listings. A user wants a sole that is flat enough, an iron that holds an edge, and honesty about rust. A collector wants the type number, the knob, the japanning, and parts that match the era you named. If you do not know the type, do not name the type. “Stanley Bailey, size as marked, sole photographed” is a listing. “Rare early plane” is a mood.
The marketplace has to match the weight. A small chisel, a few wrenches, and a block plane can go by mail if you weigh them and pad the iron so it does not punch the box. A lathe, an anvil, a table saw, and a cabinet machine are local, or they are a freight quote you get before you buy. Outlet bins price tools by the pound, which favors small marked hand tools and punishes anything you cannot identify in a minute. Garage sales are where the heavy tools belong, because the seller cannot ship them either. Ask if it runs, then ask to see it run. A story about how it ran last year is not a test.
Lots are how ordinary tools become worth listing. Ten mixed screwdrivers are clutter. Ten screwdrivers of one maker, with handles that match, are a set someone searches. Sort on the table. The sort is the work. If you will not sort, you bought a bucket, and a bucket’s sold price is a bucket.
Safety you do not get to skip
Do not buy a cracked grinder guard, a saw with a missing guard, or a tool you would not hand to a friend, and then describe it as ready for a job site. Car seats and helmets are not in this aisle, but the principle is the same as buying used: some things expire or fail invisibly, and the savings are not worth it. A hammer does not expire. A frayed cord might be the last thing it does.
Worth can read a stamp in a clear photo. It cannot hear a skipping ratchet or see a twist in a plane sole. The second look is the function. Click the ratchet. Sight the sole. Read the plate. Then decide if it is a tool you will use, which is a good buy, or a tool someone else will pay to ship, which has to clear the scale at the post office.
