Best Sander Belts of 2026

"I found the learning curve to be quick—once I read the instructions, the sharpener worked wonders. My knives are now sharper than ever, even compared to results I got from pricier alternatives. The versatility and value are hard to beat."

"I've used these Work Shop Knife Sharpener belts for years and they've proven to be reliable and long-lasting. They're a great product for anyone with the sharpener system."

"This package of belts is perfect for the Work Sharp system. The belts hold up well and are excellent for sharpening, shaping wood, and various hobbies."

"I've found that these belts last longer and offer a great variety of grits, which really helps with sharpening. The pack size is excellent, so I don't have to worry about running out quickly."

"Honestly, I think these work just as well as the brand name—if not better! There's no need to pay more when you can get this quality."

"I like that there's a wide range of grits in the kit. It really lets me experiment and achieve precise sharpening results every time."

"I’ve found these sanding belts to offer excellent value and consistent grit quality. While they don’t last quite as long as some premium brands I’ve used, the savings per project make up for it. No seam separation issues so far on my Rigid oscillating sander, and the belts track well. I’d rate the overall value as above average for my woodworking needs."

"For the price, I’m really happy with these belts. They last longer than I expected and fit my sander perfectly. I use them for both soft and hardwoods, and the grit range suits all my projects. Definitely a great deal for regular use."

"When using the 3x21” belts, I noticed the 80 grit performed exceptionally well and lasted longer than other brands. The 120 grit needed a bit more maintenance—it clogged faster and needed frequent brushing, but it still worked effectively. I recommend rotating belts to avoid overheating. Overall, the seams held up, and the durability was better than I anticipated."

"After years of struggling with whet stones, I finally tried the Ken Onion Work Sharp system. Now, I can get my knives sharper than ever before—and in a fraction of the time. The belts last a long time and handle everything from pocket knives to machetes. I even restored an old, chipped hunting knife to a razor edge. This sharpener brings back great memories and always impresses my family with the results."

"These Work Sharp belts are always my go-to because they've never let me down. Every replacement works like a charm and keeps my sharpener running perfectly. The quality is consistent, and my blades stay sharp."

"The replacement kit works well for my tool, but I wish the belts were available individually since I tend to use just two types. Otherwise, the performance is excellent and meets my needs."

"I love how these belts offer a great range of grits and keep all my knives and tools razor sharp. They're a fantastic addition to my Work Sharp sharpener!"

"These sharpening belts are a cost-effective option that delivers high quality results. My blades have never been this sharp, and I got a lot of belts for the price."

"While these belts are a bit narrower than the original Work Sharp ones, they still do the job well. The variety of grits is really nice, but next time I'll double-check the size for my Ken Onion Mk2."

"I've found these belts to be of excellent quality and just right for tight, hard-to-reach spaces on my furniture projects."

"These belts are a great money saver compared to the Dewalt brand, and in my experience with my Dewalt 20v mini belt sander, they last just as long."

"For the price, the quantity and grit variety are unbeatable. They aren't as snug on my Milwaukee m12 band file as I’d like, but at higher speeds, they work well enough to make them a fantastic deal."

"I've tried these belts as a replacement for what I used to buy at the hardware store, and I'm really happy with the fit, quality, and price. They work great with my Work Sharp Ken Onion sharpener, and the results are excellent. I plan to continue buying them in the future."

"These are a solid alternative to the original belts and work just as well for sharpening. The price is much lower than what I used to pay. The only thing I've noticed is that they might wear out a little faster, but the value more than makes up for it."

"The assortment of grits fits my unit perfectly and does the job well. The 400, 600, and 800 grit belts seem durable. My only minor issue is that the 1000 grit belt created a bit more dust and appeared more worn than the others, but overall, performance is good."

"I’ve used these belts for sharpening tools and they work extremely well on my belt sander. Installation was simple, and I appreciate the multiple grit options for different tasks."

"Honestly, the belts perform great and feel solid, but I was disappointed not to receive a single 400 grit belt, which is the one I use most often. Aside from that, the set is solid."

"As a woodworker, I value sharp tools. Using these sanding belts, I can easily create a fine bevel up to 1,000 grit—and for the price, it’s the most cost-effective solution unless you’re running a professional shop."

"I picked up these sanding belts to refinish an old coffee table that belonged to my mom. The range of grits made the project much easier, and the belts have handled even the toughest spots without losing grit. I'm especially impressed with the strong seam design—other brands I've tried snapped at the seam, but these have held up through repeated use. Switching between grits was a breeze thanks to clear labeling on the back. If you need versatility and reliability for DIY restoration, these are a great choice."

"I bought these for my new rigid sander, and the difference compared to the original belt was night and day. These belts gave my sander a much smoother operation, with seams that are barely noticeable. The variety of grit options is great for all sorts of projects. I definitely recommend them if you want to upgrade your sanding experience."

"These sanding belts are a fantastic value. My local hardware store charges double for fewer belts, and those often break quickly. I put these through some tough jobs—removing epoxy and sanding against the grain—and they held up far better than expected. Only one belt failed early, and even then, I wasn't disappointed given the price and overall quality. For the cost, these are outstanding and I'll be buying again."

"I bought these after having other belts from Home Depot fall apart within minutes, but these are so durable—I'm still using the first one!"

"Used them on my Ryobi sander and am very satisfied with the grit longevity. No issues so far, and looking forward to continued use."

"I accidentally ordered the wrong size, but the customer service was quick and helpful. Ended up cutting them into strips for hand sanding and will reorder the right size!"
