The Best Blacksmith Post Vise for Beginners

Why a Post Vise Is the Right Vise for Forging

A post vise - also called a leg vise, blacksmith vise, or filing vise - is the one holding tool built to take a beating. What sets it apart from an ordinary bench vise is the leg: a steel post that runs from the pivot down to the floor or a stand. When you hammer, bend, or twist a bar clamped in the jaws, that force travels down the leg into the ground instead of into a cast body. A bench vise cracks its castings or loosens its slides under that kind of abuse. A post vise shrugs it off, which is exactly why smiths have used them for well over a century.

That structural difference changes how you work. You can clamp a hot bar and hammer a right-angle bend, draw a taper against the jaw, put a twist in square stock with a wrench, or set a shoulder - all things that would slowly destroy a hardware-store vise. For a beginner, the vise is a genuine second set of hands, and it pairs naturally with your anvil and hammer as one of the three tools you reach for constantly. If you are still building out the shop, a post vise belongs on the short list right after the forge, anvil, and a first pair of tongs.

What to Look For When Buying

Not all post vises are equal, and a cheap one with a worn screw is a bad deal at any price. Focus on these things:

• Jaw width. This is the measurement across the face of the jaws, and it is how post vises are sized. For general beginner work, 4 to 5 inches is the sweet spot - big enough to hold real stock, common enough to find, and not so heavy it is a chore to mount. A 6 inch vise is a great shop vise but heavier and pricier. Anything under about 3.5 inches feels cramped for forging.

• The screw and screw box. The Acme-style screw and the threaded box it rides in are the heart of the tool. Thread the screw fully in and back out. It should turn smoothly with only modest play. Heavy slop, stripped or rounded threads, or a screw box that wobbles on its mount means costly repair - this is the single most important thing to check on a used vise.

• The spring. A flat leaf spring behind the leg pushes the jaws open when you loosen the screw. It should be present and springy. A missing or broken spring is common on old vises and is fixable, but factor the fix into your offer.

• Jaw alignment. Close the jaws and sight across the faces. They should meet flat and roughly square over the whole face. Twisted, chipped, or badly worn jaws grip unevenly and are hard to correct.

• Mounting height and length. Measure from the pivot to where the leg ends. Most vises mount with the jaws at about elbow height (roughly 38-42 in for a standing smith), and the leg needs to reach a solid footing at that height.

Buying New vs. Vintage

You have two honest options, and both are fine.

Vintage vises turn up at flea markets, farm auctions, estate sales, and online. Old American and English wrought-iron and steel vises were superbly made and often outlast their owners. The catch is that you have to inspect them - a pretty vise with a shot screw box is a paperweight. Prices vary widely by region and condition, so let the checklist above set your ceiling, not the seller's story. Surface rust, a missing spring, or a bent mounting bracket are usually cheap fixes; a bad screw or cracked box is not.

New reproductions are made again today, and they remove the guesswork. You get an intact spring, matched jaws, and a screw that works, with no auction gambling. They cost more than a rough vintage find but often less than a clean restored one, and for a beginner who does not yet know what a worn screw feels like, that certainty is worth paying for.

Either way, avoid a drill-press or machinist bench vise sold as a substitute - it cannot take hot work or hammering. If your budget is tight, spend it here rather than on a fancier vise you do not need yet, and put the savings toward a starter kit or a budget anvil. A vise is one of the first tools you will use on your first projects, so it earns its place fast.

Mounting: Bench or Dedicated Stand

A post vise is only as good as its mount. Because the leg is meant to carry shock to the floor, half-mounting it to a wobbly bench throws away its main advantage.

Two setups work well:

• Bench mount with the leg to the floor. Bolt the mounting bracket to a heavy, well-anchored workbench and let the leg reach down to a footing on the floor. This is the classic arrangement and gives the most rigid result.

• Dedicated stand. A short steel or heavy-timber stand with the vise bolted on top and the leg sitting in a base plate lets you place the vise anywhere and move it if needed. Many smiths fill a pipe stand with sand or concrete for mass.

Mount the jaws at about elbow height so you can hammer and file comfortably without stooping. Use grade-appropriate bolts, not wood screws, and make sure the bracket and the leg both bear load - the same care you would give when you mount an anvil. Plan the vise into your bench layout early; our shop setup guide covers where it should sit relative to the forge and anvil so you are not walking hot steel across the shop.
