Review: Happy to recommend - Likes others have noted, quality pieces of kit and well made. Needed a narrow filling knife to fill in hair line cracks in the plaster and also required for a filling wood filler in outside window cill. Handle is comfortable to hold and this will look like it will last a long time. Pricey but everything has gone in in 2025
Review: Quality piece of kit - I bought this to fill in holes an cut-outs in old door frames after replacing a number of doors in an Edwardian house. I needed a narrow filling knife so that I didn't have to take the doors off. This is ideal, just the right thickness (not too springy and not too stiff) and easy to clean, ideal for applying thin layers of wood filler. It should last a life time.
