The gold colored, limited edition, ion-plated Nepros tools and the two previous ion-plated series all have a common theme. That is, they are tools to be used. The ion-plating, which was a process developed by NASA in the 1950's, is an additional surface finish that goes on top of the double-nickle chrome plated finish. Whey ion-plating? For greater surface finish durability. In terms of hardness of the ion-plating, it's 2 to 3 times harder than the standard chrome plated finish.
This current series is apparently limited until Sept 1st, 2022.
I can't remember if the IP-black and IP-blue were sold as individual peices, but for now, the gold series stuff is primarily sold as sets.
In the past, after a few months go by, I've noticed individual items being available for sale on some Japanese online merchants.
Perhaps if DRPD purchases a large set, and there aren't any buyers, they could break up the set to sell them individually down the road?
