I'm always dubious of any products with exclamation points in their title, so I approached the Scor-Pal! with caution.
I was originally contemplating purchasing a Scor-it. Both are products designed to make the scoring (and folding) of paper easy and precise. This work can be done with a ruler and a bone, but after having folded 60 thank you notes for a recent order, I wondered if I could simplify production with a simple tool.
I posted a note to my etsygreetingsteam discussion board and soon I had received a lot of pros and cons for both. One very helpful link lead me to this critique of both products: http://www.craftcritique.com/2008/03/sound-off-scor-pal-vs-scor-it.html
Based on a lot of opinions, I ended up purchasing the Scor-Pal! exclamation point and all.
It's not much to look at, just a piece of plastic with a bunch of grooves on it, but dang it! It sure has been handy already! I took some photos of it in use, above. If you click to enlarge the photos, you can see the very nice, straight fold it helps to create, resulting in a very happy ghost card.
This little device will also eliminate cracking of heavy cardstocks when they're creased, as well, and enable me to do some fun projects, like accordian fold cards.
Here's a link to the Scor-Pal! site which includes some interesting looking projects (the site's a little clunky, but there are still some good ideas on it): http://www.scor-pal.com/projects.htm
So, my opinion: two thumbs up! A great product if you're doing a lot of production work on cards. It will save you time and also make your products look a little more professional.
