Ferro rod sizes for wholesale buyers: a chart of the diameters and lengths we make, which size suits which product, and when a rod can be drilled.
Most Ferro rod inquiries we get start with a size. Sometimes it’s metric, sometimes it’s “1/2 inch by 5 inch with a 4 mm hole”. Both are fine. The trouble is that a size on its own doesn’t tell you whether the rod suits a keychain, a camp kit or a gift box.
Ferro rod size is diameter × length. Thin, short rods (around 6 mm) suit keychains and compact kits. 8 mm rods are the common all-rounder for handled kits. 10 mm and up suit large camp rods and bare-rod kits. Rods from 6 mm diameter up can be drilled, and 4 mm is the common hole size.
Below is the chart of sizes we actually make, then how to pick one and what to send for a quote.

A size is two numbers: diameter first, then length. “8×70 mm” means an 8 mm thick rod, 70 mm long. US buyers often write inches, so “1/2”×6”” is about 12.7 mm thick and 152 mm long.
One thing to watch: with a handled rod, the length usually means the rod, not the whole tool. If you are comparing two quotes, ask whether the length is rod-only or overall. If you are new to the product, what a ferro rod is is a good place to start.
These are the rod sizes in our current range. Each model family has its own handle, striker and packaging options.

If a buyer’s spec isn’t on this list, send it anyway. We’ll tell you plainly whether we can make it or which size is closest.
Go small. A 6 mm rod keeps a keychain light and pocket-friendly. FS25 is built for this.
The 8 mm rod is the common choice for wood or aluminium handles. It fits a hand well, and it’s the size most of our kit models use, so you have the widest choice of handles, strikers and pouches.
For a larger rod that sits in a pack or a kit box, look at 10 mm and up. The 10 × 100 mm rod covers most bare-rod kits. The 10 × 150 mm, FRC21 and FS12 are the big ones.
Here the box or pouch often decides the size. Measure the space first, then pick the rod.
A handle gives the buyer grip and gives you a place for a logo. A bare rod is simpler and packs flatter. If it will hang on a lanyard, it can be drilled (see below).
Logo placement matters here. We do not put a logo on the rod itself. A laser logo goes on the handle or on the striker, from 50 pcs. The full process is in our guide to custom logo ferro rods.
Yes, we can drill ferro rods. Usually the rod needs to be 6 mm in diameter or more before we drill it. The hole size is your choice; 4 mm is the common one, because it takes a split ring, a lanyard or a small cord loop.
One buyer put it simply: “i want 1/2 inch x 5inch with 4mm hole”. That’s a good inquiry. It gives diameter, length and hole in one line. If you want a drilled rod, add the hole size and where it should go, and tell us what will go through it.
For larger volumes, see our page on bulk ferro rods.
Start from the product: a 6 mm rod for keychains, 8 mm for most handled kits, 10 mm and up for large camp rods. Add a drilled hole if the rod is 6 mm or more and needs a lanyard.
