My 2 cents (worth 1 maybe)
Mizuno's forgings had the best feel, of any iron I hit. But I could not play with them. i do not produce much back spin
and the Mizuno's HAD pretty passive grooves. Did not control my distances well.
Bridgestones Blades Gorgeous. Not as soft feeling as Mizuno, but pretty controllable.
Honma Best looking of the bunch to me, but a little hard feeling
Cleveland Good feel, but "stick" in the ground a little. Custom ground the soles to get them to "cut" through better. Very good
Titleist blades. Good looking, pretty passive grooves also. Feel a little harder than Miz
Callaway X blade Love these. Long irons a but unforgiving, but short irons are money. New (legal) grooves were plenty, even for me
Ping Not really blades, so nope. But I like their "version"
Miura WOW! Just hit one today ironically. Beautiful, and may be as solid feeling to me as the Miz
Have not hit the Scratch yet
