The English pattern is a common type of extraction forceps. It is important to know that within this design, the figure number (like 4) corresponds to a specific tooth type and arch. While a size 4 forceps is used for lower anterior teeth, the available search results do not confirm its availability with the diamond coating feature.

If you require a diamond-coated English pattern forceps, I recommend contacting a dental supplier directly to confirm if they can source a Fig. #4 with this coating or find a compatible alternative pattern.
