Is a 2×72 better than a 2×48 for knife making?

For most knifemaking, yes — cooler belts, more jigs, and enough loop for kitchen-length blades. A 2×48 is a legitimate smaller machine for short blanks and tight benches, not a failed 2×72.

Can I use 2×72 belts on a 2×48 grinder?

No. The loop length is different. Buy belts that match the machine. If the listing does not name the size, write to us before you order.

Do belt grinders get free shipping over $150 CAD?

No. Belt grinders always ship at 15% of the item price and never qualify for free shipping. Belts, jigs, and steel still follow 10% / free over $150 CAD. Delivery is typically two to four weeks.

Should a beginner buy a 2×48 to save money?

Only if space and belt cost are the real constraints and you will make short knives. Saving money on a 1×30 hardware sander is the false economy. If you can fund a variable-speed 2×72, that is the machine the rest of the hobby is built around.

Is a belt grinder a kitchen knife sharpener?

No. A knifemaking belt grinder forms bevels on annealed or heat-treated blanks. Kitchen sharpening belongs on a whetstone or a guided stone system. A belt will overheat a thin VG-10 edge if you treat it like a gadget sharpener.

2×72 vs 2×48 Belt Grinders for Knife Making

8 min read · By The Knife Vault Editorial Team

Belt size is the first machine decision in stock-removal knifemaking, not horsepower bragging. A 2×72 (two-inch by seventy-two-inch belt) is the hobby-to-small-shop standard because belt selection is enormous, the loop runs cooler, and most jigs assume that length. A 2×48 is a shorter loop: less abrasive in circulation, smaller footprint, belts that cost less each — and less forgiveness on a long chef blank.

The stock-removal pillar assumes a belt grinder, not a forge. The beginner knife-making kit dossier is the shopping order. This page is the 2×72 versus 2×48 comparison against machines we actually list, priced in CAD.

01 Direct answer

Buy a 2×72 with variable speed if you are making knives as a craft — especially kitchen-length blades, distal tapers, and any jig you might add later. Buy a 2×48 if bench space and belt cost matter more than speed, and your blanks stay short. Do not buy a 1×30 hardware-store sander thinking you will upgrade later. Confirm 110 V versus 220 V before it ships to a Canadian shop.

02 What the numbers mean

The first number is belt width; the second is loop length. Two inches of width is enough for most knife bevels and handle work. Seventy-two inches of loop means more abrasive in circulation, more time for the belt to cool, and a parts ecosystem (contact wheels, platens, small wheels, tool rests) built for knifemakers. Forty-eight inches is a shorter loop: the same two-inch width on many machines, less cooling, fewer aftermarket jigs, cheaper belts.

Variable speed is non-negotiable on either size. Hog annealed steel at high speed; finish, sharpen, and work handle materials at low speed. A single-speed grinder burns tips and tempers. Motor size: 1.5 to 2 HP is the 2×72 sweet spot; under 1 HP you will bog in hardened steel.

03 Head-to-head

Use this table as a shop filter, not a brand ranking. Listings on this shelf mix 2×72 and 2×48 machines; read the belt size on the product page before you compare price.

2×72 vs 2×48 for stock-removal knifemaking

	2×72	2×48
Belt	2 in × 72 in loop	2 in × 48 in loop (typical)
Cool cutting	More abrasive in the loop; belts last and run cooler	Shorter loop heats faster; change belts sooner
Knife length	Comfortable on 8-inch chefs and longer tapers	Fine for short camp and EDC blanks; slower on long kitchen blades
Jigs & parts	The hobby standard — most attachments assume 2×72	Fewer purpose-built knifemaking jigs
Belt cost each	Higher per belt; huge selection (ceramic, Trizact, slack)	Cheaper consumables; narrower catalogue
Footprint	A real bench machine	Smaller; still a machine, not a toy
Who it is for	First serious grinder, production-curious hobbyists	Tight space, short blades, belt-budget constraint

Qualitative comparison for knifemaking, not a lab test. Voltage, VFD, and platen quality still decide more than the inch marks. 2×36 and 1×30 hardware sanders are a different, worse class for this job.

04 Pros and cons, plainly

◆ 2×72 — pro: cool grinding, belt selection, jig ecosystem, kitchen-length blanks. Con: price, footprint, heavier freight.
◆ 2×48 — pro: smaller bench, cheaper belts, enough machine for short knives. Con: hotter loop, fewer attachments, slower on long bevels.
◆ Either — skip fixed-speed, skip mystery belt size, skip a 1×30 “upgrade path.”

05 Machines and belts on this shelf

2×72 examples we stock: the 2×72 variable-speed belt grinder and the SucceBuy 1500W 2×72 belt grinder. 2×48 examples: the 2×48 knife-making belt grinder and the ADV 2×48 belt grinder. Belts are a separate order — 2×72 belts will not fit a 2×48. The Remoba 2×48 sanding belts are the short-loop consumable on the knife-making counter.

Read voltage on the listing. A 220 V / 380 V machine will not plug into a standard Canadian 120 V circuit without a plan. The belt grinders hub is the hardware comparison; bevel grinding is the step at the platen.

06 Freight: 15%, and it is never free

Belt grinders are large workshop equipment. They always ship at 15% of the item price and are not eligible for free shipping, even when the machine itself is thousands of CAD or the cart is huge. That is a different rule from knives and small goods (10%, free over $150 CAD). Mixed carts charge freight on the machine plus the usual rule on belts, billets, and stones.

Typical delivery is two to four weeks, tracked, in plain packaging. Adults 18+. These are shop tools, not weapons. If voltage or belt size is not written, write to orders@knifevault.ca before you order into a Canadian shop.
