ROLLINGDOG Joint Knife Review (Filling Knife)

ROLLINGDOG manufactures a couple of different joint knives, but as a professional decorator, I know products like this as “filling knives”. I use them for repairing imperfections on plaster, render, timber and other substrates before painting over them. They’re perfect when using Toupret, Oxera, or any other filler.

I’m going to keep this blog nice and short, but I’m going to cover two products from ROLLINGDOG. The first is theDoberman Joint Knife, and the second is the Ultra-Flex.

ROLLINGDOG Doberman Joint Knife Review

I must say, this is a fantastic-looking filling knife. It consists of a flexible stainless steel blade and a solid wooden handle. The blade runs through the whole length of the knife, and the handle simply encloses one end.

There is a laser-engraved pattern and branding on the wooden handle, which I know doesn’t add to the performance of the tool, but it just gives you an idea of how well made the ROLLINGDOG Doberman Joint Knife really is.

The filling knife is well balanced and comfortable to hold. You can use it for long periods without experiencing unnecessary strain on your hand or arm.

 ROLLINGDOG Ultra-Flex Joint Knife Review

This filling knife is equally well made. It has the same stainless-steel blade, which runs all the way from one end of the knife to the other. However, unlike the Doberman, this one has a soft-touch plastic grip handle with a heavy stainless-steel flat end. It feels chunkier in your hand, but it means you can use the end to tap protruding nails back into timberor push wall plugs into the wall. The blade is also more flexible, making it ideal for applying filler to larger areas. It’s another quality bit of kit, and one I enjoy using.

Review Summary

FAQs

What is the difference between a filling knife and a stripping knife?

A filling knife is more flexible, allowing you to properly work the filler. A stripping knife (also called a scraper) is more rigid and will withstand more of a battering. You can strip and scrape with a filling knife, but you’d struggle to fill with a stripping knife.

What is a filling knife used for?

A filling knife is used to apply filler to walls, ceilings and woodwork. You can also use a filling knife to apply putty to windows.

Can you use a filling knife as a scraper?

You can. In fact, filling knives often work very well as scrapers. However, they won’t handle heavy-duty tasks like stripping paint, and they may get damaged or scratched over time.

How do you clean a filling knife?

Just rinse it in warm water and wipe with a cloth after use. If filler has dried on the knife, simply soak it in hot water for an hour. The filler should then come off easily.
