Sean McHugh founded McHugh Milieux in 2011. Sean McHugh was trained by Charles Scouten PhD, inventor of the first commercially marketed retractable wire knife carrier and knives (formerly manufactured by David Kopf™ as the model 120 Knife carrier and Model 121 and Model 122 knives). (Scouten, Cegavske and Rozboril, 1981)
David Kopf Instruments™ no longer manufactures the retractable wire knives. McHugh Milieux products are made to a consistent and reproducible specification and are fully reliable. McHugh’s retractable wire knives are currently being used in research.
