LH must really be hurting for content ... good grief.

Next up: how to re-use a velcro tie???

Most zip ties do not have a protruding lip for fingernail access. Most of them are one time use. A small flat screw driver works best regardless of the type and can actually be used on the front or back depending on accessibility and circumstances.

However, in most cases it is not worth it to release the zip because the excess of the tie has been cut, so you're not going to reuse it to tie the same thing, unless you are taking content out and need a smaller loop. I typically only try to save / re-use some of the really big and expensive ones. For the rest I buy them by the thousand and it is snip, snip, zip, zip, trim, trim done.
