This is the most popular and versatile hobby knife I have found. It has a nice grip and blades are easy to interchange. They come in different colours so one can always use a particular colour for a particular task. For example, my green one always has a new blade and I use a red one when I have something that can use a slightly worn blade.

I recommend having three or four of these on the go at any one time. That way, there is always at least one with a very sharp blade.

Please note the website has a single flat-rate for the shipping and it is quite high relative to a small item such as a single knife. Please consider grouping your purchases.

Thanks!
