ultra knives
and their applications

	Highest quality diamonds and optimal crystal orientation guarantee perfect ultrathin sections and a durable cutting edge
	Section pick-up is facilitated as the boat is horizontal allowing the water to completely fill the boat all the way round
	A hydrophilic surface makes it easy to wet the cutting edge, even with low water level
