<div dir="ltr">Bob,<div><br></div><div>At one point I was involved in making surgical scalpels from silicon, and this required putting a beveled edge in silicon (15 or 20 degrees, just like cutlery) and then chemically sharpening the edge. I would purchase wafer dicing blades which had an angled edge to them instead of being flat. I would get these blades from Thermoccarbon in Casselberry, FL. You could ask them if they'd be willing to sell you some 45 degree'd blades; my guess is they make these.</div><div><br></div><div>ThermoCarbon: <a href="https://dicing.com/">https://dicing.com/</a></div><div><br></div><div>Regards,</div><div>Kevin</div><div><br></div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, Sep 1, 2023 at 11:38 AM Geil, Bob <<a href="mailto:bob.geil@unc.edu">bob.geil@unc.edu</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div class="msg1474662303929680033">
