Plastic surgery is exacting in all its requirements; always so as to technic, often so as to instruments. Skin grafting is exacting in both regards.
The greatest difficulty one has in cutting Thiersch grafts is in procuring a satisfactory cutting instrument. I have devised a knife that is simple and inexpensive and that serves the purpose well, giving a sharp edge at all times. It can be made in a few minutes, if necessary, from materials procurable anywhere.
From the guard of a Durham Duplex safety razor, I removed the teeth from the left side at the line where the teeth join the body of the guard. This straight edge was then beveled, and the outer end was also beveled to facilitate the removal of the grafts from the knife. This completes the instrument. A guard which has a wider surface than the one ordinarily supplied may be provided.
