If you enjoy making cards or hand-made books, this tool is a wonderful addition to your tool box. I own the large base unit, and while I don't keep it on my work table all the time due to it's large footprint, I do pull it out and use it often.

I love how it makes consistant, crisp scores a piece of cake. The ruler mounted at the top is designed with a "0" center mark to make locating the center of your work a breeze. and the "stop" jig allows you to measure once, set the jig, and make as many card blanks, or book pages as you wish at that size without even thinking about where that score line has to fall.

Actually making that score line is simple too. Just lay your work over the metal "blade" butted up agains the "stop" jig, Insert the grooved tool into a slot milled out of the base so that it straddles the scoring blade and slide it down the blade, over your work. Voila! a perfect score line!

Just fold, smooth and you're done!

And that little grooved tool won't get lost either because some smart designer included a length of ball chain that attaches the tool right to the base so they stay together. How cool is that?

This tool is a bit of an investment, but if you do a fair amount of scoring, in my opinion, it's worth it.
