Tee hee, tee hee, tee hee. the mental image! couple of more things: Don't clip with nail clippers, can shatter the work you so dearly paid for. the tech SHOULD give you the file she used on you, unless it is autoclavable. That's the law in California, anyway. That, or break em in half, and throw them away. to clean out crud from the underside......you can GINGERLY use a dremel tool. It is quite similar to the "drill" i used in the salon. And that twas the only thing i used it for. Run if you see some one who wants to topfile with one, you can get burnt REALLLY fast.
