One Tersa carbide head is retail at 20-150$+. For my planer it¡¯s 150$.?
It takes a few minutes to turn the segmented heads. You get 4 turns before the head is worn.?
You turn one carbide silent power segment, and while it may take longer. You have 4x the cutting life.
Time is money yes, a silent power cutter head potentially saves 4x Tersa changes or in my case 450$ per full blade change.?
I don¡¯t make 450$ per hour. ?

"Why would tersa be a better option vs Felder silent power?? With a carbide cutter you can just rotate the cutter¡.."
Because most people don't value their time at $0 / hr.
By the time you've rotated 2-3 segmented cutters and properly torqued them, the Tersa owner has knocked down a couple of wedges and replaced all 3 or 4 blades on his cutter head and is back to planing.?? So, the more often you need a new cutting edge,? the Tersa user banks time savings at an exponential rate.
I have not conducted a study or seen any data on whether a Tersa knife edge lasts longer than a segmented cutter edge or vice versa? - so I have to hedge my over all cost benefit judgement pending solid data.
