From what we've gathered, the Faithfull FAISGPKME Soft-Grip Putty Knife seems to have been designed with comfort in mind. It features a soft-grip handle that the manufacturer highlights for providing comfort and good control while you work.
If you're going to be using it for long stretches to apply putty or filler, the handle is probably a nice touch, as it's said to help minimize hand fatigue.
The stainless steel blade is a strong point too, being known for its durability and resistance to rust. This makes it not only comfortable to use, but also pretty tough, which is always a plus if you're looking to add something reliable to your toolkit.
And hey, the metal end cap is handy for tapping down nails, which adds a bit more versatility to the tool.
One thing to keep in mind, though, is that it doesn't come with a carrying case. So, if you need something easy to transport or store neatly, you might want to consider picking up a tool case to go along with it.
All in all, it sounds like a solid choice for both DIY fans and professionals who appreciate thoughtful design and efficient function. But if the lack of a carrying case is a concern, you might want to check other options that include this feature.
