ROLLINGDOG Joint Knife Review (Filling Knife)

Updated Jun 16, 2024 | Posted Feb 22, 2023 | Product Reviews, Tools | 1 comment

ROLLINGDOG manufacture 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. They’re perfect when using Touptret, Oxera, or any other filler.

I’m going to keep this blog nice and short, but I’m going to touch on two products from ROLLINGDOG. The first is their Doberman 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 crafted wooden handle. The blade runs through the whole length of the knife, and the handle merely encases 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 and 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 any 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-plastic grip handle with a heavy stainless steel flat head to it. It feels chunkier in your hand, but it means you can use the end to hit nails out of timber, or push raw plugs into a wall. The blade is also softer. It’s another quality bit of kit, and something I enjoy using.

Final Thoughts


Up until recently, I hadn’t even heard of ROLINGDOG Joint knives. Now I’ve been using them for a few weeks, I can safely say they’re a step-up from anything else I’ve used. Whether you go for the Doberman, or the Ultra-Flex, you’re buying quality. Click here for a full price list.
