We have the older version of GKM triangular glass knife breaker, formerly 
under Sorvall (original manufacturer) name.  1/4" knives were made for 
cutting EM resin thicker sections, 1/4, 1/2 and 3/4" knives for glycol 
methacrylate embedded tissues.

The joy of the knife breaker -  it has been in our dept for over 25 years 
after heavy usage and needed parts, cleaning, basically reconditioning. It 
has been a workhorse, simple to operate, easy to use, and totally 
reliabled. Best of all - it has NOT been discontinued so service, repair 
and replacement parts are still available (our bills was minimal (less than 
$400) considering the units age and heavy use.   The service from Energy 
Beam Sciences was excellent, prompt and Cindy Gaspari was very helpful. One 
can also purchase a little kit to replace the glass scoring wheels  in 
house.  You can go to their website for pricing, view the unit, etc.

Although new units are pricey, and if I had to buy one based on company 
service, ease of use, but mainly unit longevity, it would be the now GKM 
aka Sorvall unit.  It has been a excellent investment without downsides.

Hmm does this sound like a sale pitch!  Well, EBS can enjoy it from a happy
