Brush Research embraced the benefits of a plateau finish and pioneered the concept of plateau honing culminating in the introduction of the Flex Hone tool in 1972.

The Flex-Hone® tool was originally created by Brush Research Manufacturing to deglaze cylinder walls in automotive applications. Brush Research embraced the benefits of a plateau finish and pioneered the concept of plateau honing culminating in the introduction of the Flex-Hone tool in 1972. The Flex-Hone has gained many nicknames over the years and including ball hone, ball style hone, flexihone, dingleberry hone, bead brush, glaze breaker and glaze buster. Flexible honing with the Flex-Hone tool produces an oil holding cross hatch pattern and a true plateau finish free of cut, torn and folded metal. Any type or size of cylinder can benefit from the Flex-Hone®. These abrasive bead style brushes are produced in standard diameters from 4mm to 36 inches. Nine abrasive types are offered including silicon carbide, aluminum oxide, boron carbide and diamond allowing the tool to be tailored to finish any base material. A choice of 11 different grit selections are available for precise control of finish parameters. The elimination of peaks results in rapid ring seating, better oil control, reduced seepage in hydraulic and pneumatic applications and provides better seal performance and longer seal life. Successful applications include firearm chambers, shotgun barrels, musical instruments, combustion chambers, air compressors, pumps, valve bodies, valve guides, brake cylinders, wheel cylinders and the list goes on and on. Flex-Hone® tools are also very effective for deburring cross drilled holes, port radiusing and edge blending. Because of its unique construction, the Flex-Hone is self-centering, self-aligning, and self-compensating for wear so it does not require an elaborate set-up or special training. Deburring can be effectively automated and combined in the machining process to allow a complete cylinder finish in one operation or it can be employed as a secondary operation with equal results.

Highly recommended for any owner of a "Super Chewer."
Rating: ⭐⭐⭐⭐⭐ (5/5) Title: Finally, toys that can actually withstand my Labrador’s jaws! If you own a "power chewer," you know the struggle: you bring home a new toy, and within ten minutes, it’s shredded into a thousand pieces of foam and plastic. After going through countless toys that promised durability but failed within a day, I decided to give the WOWBALA 2-Pack Indestructible Dog Toys a try—and I am genuinely impressed. The Durability Factor The biggest selling point here is the material. These are made from high-density, food-grade nylon, and you can feel the quality the moment you take them out of the package. They are solid, heavy-duty, and have held up perfectly against my Lab’s relentless chewing. Even after a week of heavy use, there are only minor surface marks where his teeth have made contact, rather than the dangerous chunks that usually break off other toys. Design & Engagement The pack comes with two different shapes—a stick and a ring—which is a great variety. The curved, ergonomic design of the stick makes it very easy for my dog to hold between his paws while he chews, and the textured surface seems to really hit the spot for him. I’ve also noticed that it helps keep his breath fresh and his gums healthy since the texture acts almost like a toothbrush while he plays. The "Milky" Scent One thing I was initially skeptical about was the "milky scent." I wondered if it would be overpowering, but it’s actually quite subtle. It was strong enough to immediately pique my dog’s curiosity right out of the box, but it doesn't leave a weird smell on my carpet or hands. It’s clearly effective, as he keeps coming back to these toys even when he has others scattered around the room. Peace of Mind Beyond just being tough, I appreciate that they are non-toxic and dishwasher safe. After a long day of outdoor play in the mud, being able to just toss these into the dishwasher and have them come out clean and sanitized is a huge convenience. Final Verdict If you have a medium to large breed dog that loves to destroy everything in sight, these toys are well worth the $15.99 investment. It’s rare to find a product that lives up to the "indestructible" label, but these truly do. They’ve been a lifesaver for keeping my dog occupied while I’m working from home, and it’s a relief not having to play "clean up the debris" every evening. Pros: Extremely durable high-density nylon. Great value (2-pack). Easy to clean (dishwasher safe). Engaging design for teething, training, and boredom relief. Safe and non-toxic. Cons: Because they are hard nylon, be careful using them indoors on hardwood floors—they can be a bit noisy when dropped! Highly recommended for any owner of a "Super Chewer."

These are way better than I expected and hold up to our aggressive chewer spectacularly!
I got these specifically for our newest pup (an 8 month old lab/pitbull mix--she's a big puppy, lol) who is obsessed with toys and chewing. She has a tendency to go through her toys quick, both chew toys and soft ones, so I wanted something that would last a bit longer for her because I can tell she gets a bit sad when we have to trash one that's hit its lifespan. So far, these have been a big hit! They're the perfect size for her to pick up, the chicken claw-style texture is great for both keeping her interested and giving her some grabbing options, and they do seem to hold up to their claim of being made for aggressive chewers! There's obviously some wear, but it looks like expected chew toy wear; no claws have snapped off, and her chew marks look relatively minimal compared to what she's done to other chews. I also appreciate that these came in a two pack; we have a smaller dog, and while these are technically big for him, he enjoys having one to play with and chew on as well. These have been a pleasant surprise and I actually think I'll come back to buy them again whenever they're spent! Definitely a worthy purchase!
