Swann Morton non-sterile safety scalpels combine a preloaded stainless steel blade with a retracting guard that covers the cutting edge. Supplied in boxes of 500, they are available in eight blade sizes so you can select the profile required for your work.
The guard is a handling safety feature; follow the manufacturer's instructions and your workplace sharps procedures. This is a non-sterile product, not a sterile surgical scalpel.
