Re: takeuchi trs-101 floyd rose question
Yes, the knife edge is part of the base plate.
Fwiw, I have one of the same ilk (Lo TRS II) on my Ibanez - heavily used for the last seven years and it works well, despite the wear. One problem with these, from an engineering standpoint, is that sometimes the knife edge is too thick for the posts, which prevents the trem from returning to the zero point, thus impeding tuning stability.
One way to cure this is Chapstick and/or filing. When I got the guitar, I performed the Chapstick treatment and it worked out. These days I don't need to do it because the trem has thoroughly worn in. Though I am waiting for the day it starts giving out, going into year eight it shows no serious sign of functional impairment
As far as I know, these TRS derived trems are not of a hardened steel used by Floyd Rose, Gotoh, etc. so wear is going to be more pronounced over a shorter period of time. I've had to replace most of the saddles on mine because the area where the string rests upon being clamped by the locking block wore out, so the strings couldn't be locked anymore.
So, in all, if you want performance/longevity, then it's probably better to invest in something better, as Zerberus says. Depends on how heavy a user you are too.
