I've been in touch with several companies that I recognize (Schmidt and Moore and a couple other) regarding custom knives for a moulder head. Specifically stile and rail knives. It seems the range of prices is pretty narrow and in the $290 - $320 per knife set (total of 4 knives). Does any one have another source that charges less? The cutter head is a 1.25 bore x 2" tall x 4 diameter. It accepts standard 5/16 corrugated knives. Thanks for any help!
