[Nhcoll-l] Tissue subsampling scissors

[Simon Moore]

Decoupage scissors are good for this type of work, particularly if they have finger guards on the handles.  The spring keeps the scissor blades open once you’ve taken a micro-snip.  They range in price considerably but at the lower end shouldn’t be more than 5 to 10 bucks apiece.
 
With all good wishes, Simon.

I know some people use scalpel blades but I prefer fine dissection scissors as they not only provide a finer manipulation but also (in most cases) negate having to remove the tissue from the original tube an thus avoid additional contamination possibilities.

So, we are considering purchasing ceramic coated tungsten carbide scissors such as these:  https://urldefense.proofpoint.com/v2/url?u=http-3A__www.medicalresources.com_shopping_proddisplay.asp-3Fcatalogid-3D18330&d=AwIF-g&c=-dg2m7zWuuDZ0MUcV7Sdqw&r=CLFZJ3fvGSmDp7xK1dNZfh6uGV_h-8NVlo3fXNoRNzI&m=oxxqzg2sriGmdC2LBUqDsr7i1AtHnQl2iPdF9qcHw5w&s=dJFm8BvQnAoxph4_YJ8GM49tm0MdS5ZNxIk_ydgtGZ4&e=  – which are purported to be six times more durable than regular stainless steel varieties.  They are however VERY expensive and so, before diving in I thought I would ask around to see what others are using.
