Silhouette has a list of tools that you can buy, but they look like things that you may already have around the house.  If what you have doesn’t work, you should try theirs.

Hook

• Tooth scaler and pick

Scraper

• Pot scraper
• Egg turner with tapered edge
• Old credit card

Spatula

• Clay forming tools
• X-acto Knife
• Thin, non-serrated plastic knife

Pick-Me-Up

Now, I have not tried this yet, but I wonder if spray adhesive on an unused eraser on a pencil would work.  Certainly worth a try, I think.  :)
