Start with a sloped CF row or a rounded U profile around your established hand movement. The finer 0.18 mm wire and fuller 0.25 mm choices give another comparison at the same shape and point count. These manual blades use 304 stainless steel and EO sterilisation.
0.18 mm ten-pack — introduce a fine-wire configuration
Start with 12CF for a smaller sloped-row configuration or 14U for a curved working profile. Choose by the stroke shape and span your manual technique uses, keeping the wire at 0.18 mm across this range. The ten-blade pack is a focused way to introduce a configuration.
Super Black — compare wire size within a regular twenty-pack
Choose Super Black when a regular 20-blade supply and a choice of 0.18 or 0.25 mm serve your manual workflow. Compare 14CF 0.18MM with 14CF 0.25MM for the same sloped shape and count, or the two 14U diameters for a rounded edge. Start with the shape you guide most confidently, then choose the needle body; pair the selected blade with its matching manual holder.
