BLADES
Manufacturers have created blades that reduce noise, resulting in a quieter, safer work environment.
"We have a diamond blade that is an all-combination blade that will cut anything," Hunkler says. "Masonry contractors tend to cut a lot of different materials. This saves them a lot of time. They don't have to switch blades. Anybody can grab it and cut with it."
Hunkler says since the blades can cut a variety of materials without getting damaged, contractors won't have to buy as many blades. "It isn't a cheap solution. It's a long-term solution that will save money and time in the long run."
Diamond Vantage has a new multipurpose blade, AllCut, that can cut masonry, steel, stone and concrete, among other things, Gilmour says.
"It will cut through rebar and wood quickly," he says. "You can keep the blade on the jobsite to cut limestone, and then cut rebar."
Delahaut expects that general-purpose blades will become the norm over the next decade.
"If I look out over the next 10 years, I think we'll end up with only few blades that will be able to cut nearly every masonry and stone material found on most jobsites," he says. "Most of the specialized blades today will evolve into a general-purpose blade. This will give so much more versatility to the contractor."

Reduced noise
MASONRY BLADES tend to leave a high-pitched ringing in the user's ears. Manufacturers have responded with blades to reduce that noise, resulting in a quieter, safer work environment.
"We carved out pieces of the steel core and filled them an epoxy resin," Gilmour says of the Silent High Speed Zenesis blade. "That deadens the sound and makes it quiet."
Husqvarna offers Silent Runner blades, available in five grades of hardness, including the new S10 blade for general-purpose block and soft brick, that produce less noise, Siva says.
"These blades have a sandwiched steel core, so the core itself has three layers that absorb the harmonics," he says. "It prevents vibrations in the steel core, which is the best way to reduce noise."

DUB'L LOOP-LOK
Reinforcement System
100% protection against separation of wire tie from reinforcement.
Allows in-plane vertical and horizontal movement of masonry wythes while restraining tension and compression.
Loops welded shut to maintain allowable tolerance and system integrity.
Unlike horizontal eyelets, vertical loops will not clog with mortar as construction progresses.
Loop extends one direction only to allow simple placement of insulation.
Slip on Loop-Lok™ Washer to mechanically lock insulation in place.

MIGHTY-LOK™
High Strength
Large diameter eyelets and pintles afford usage where high strength requirements are present and standard eyelets and pintles would fail (including extra-wide cavity conditions). Also designed for usage where standard eyelets and pintles would fail due to greater than normal misalignment of mortar joints between the 2 wythes
Rounded eyelets engage pintles snugly in conformance with existing codes (less than 1/16" mechanical play). No oblong-shaped eyelets as found on other systems
Available Truss style (#170-ML) or Ladder style (#270-ML).
