I got some of these blocks in blue and red. Just finishing up a blue handle now and it's turning out great. Lovely colours, patterns, really nice to cut and grind (very wear a mask), quite pricey but good on sale. Very chuffed with the blocks, definitely great for a pretty project :)
You can tell that the file guide is of high quality just from its packaging. It comes in a quality metal case with a graphic of the guide on the lid. All the components have their own place in the custom cut holes in the dense foam. Very nice.
