I don't like the sound of this.  Such work is best done by a
person with experience in it, and knowledge of sterile work
basics.  In my view, do-it-yourself, is probably a bad idea.

A couple of things come to mind when I read this.  This advice
neglects a few details, like cleaning the site before you clip and
remove sutures.  Further, this is a two-hands operation, and
given sutures in a finger, one hand is not available.  *At least,*
find a knowledgeable friend to do this work.  And, do it late in
the healing process after the closure has developed some
strength.  Best of all, take it to an expert.  Economy on this
detail may prove to be no economy at all.
