BLOCK SHEAR™ is a line of highly-productive portable hydraulic
tools for the masonry and landscaping trades, that provide
on-site, precise split-face cuts on all types of cast and
natural stones, including specifically:
1.Natural Stone
2.Curb Stone
3.Cast-Stone
4.Concrete Masonry Blocks
5. Veneer Stone
6. Mosaic tile
7. Brick Pavers
8. Wall Stone, including the
toughest, Granite and Quartzite
BLOCK SHEAR™ portable
stone working tools vastly increases the speed of splitting and shaping of
large and small stones of all above types, with large labor
savings. Typically, the payback period is only a few weeks. The
increase in efficiency that this equipment delivers is so
significant that it usually pays for the equipment cost on the first
project.
BLOCK SHEAR™hydraulic splitters are activated either manually or Air-assist-Activated. In either variant, it’s the hydraulics that turn our splitter into power tools, as compared with still commonly used labor-intensive (manual) block and stone cutting and splitting methods.
Please read on to learn why BLOCK SHEAR™ portable machines are the favorite of stone masons and landscapers worldwide.

LACKNER TOOLS TM, including
the BLOCK SHEARTM line of stone working tools and block
working tools, created by Raymond Lackner, a multi-talented industrial executive and
consultant, and before that an experienced CPA. Amongst his various designs are steel laminate/fabricated component parts that replace cast steel parts for boom cranes and
forklifts and a line of patent-protected, very cost-effective industrial refuse compactors for the solid waste industry – the latter are sold internationally. Mr. Lackner licensed those
inventions to companies in different countries, who manufacture them on a royalty basis.
When he began to create / invent, design and detail-engineer the present BLOCK SHEARTM hydraulic construction tools, Mr. Lackner decided to go into manufacturing for himself. He
now co-owns and operatesthe company that makes them. You are now visiting its website. This This company, our Stone Working Division of BLOCK SHEAR LLC. also sells its products internationally.
Our Small Equipment Division focuses on manufacturing hydraulic tools and equipment
for splitting cast stone (masonry), natural stone and slab construction materials. See above
the detailed list of applicable construction materials.
BLOCK SHEAR™ portable machines -- hydraulic masonry equipment and hydraulic stone
splitting equipment (hydraulic splitters) – quickly became the favorite of stone masons
and landscapers worldwide.
Our hydraulic stone / block splitter
tools are activated either manually or as air-assisted
activated. In either variant, it’s the hydraulics that turn our splitters into power tools,
as compared with still commonly used labor- intensive (manual) block and stone cutting
and splitting methods.
Our hydraulic splitters are portable but robust, as are all tools and equipment designed by
Mr. Lackner. LACKNER TOOLS™ represent good value because they are very practical.
The payback period on BLOCK SHEAR™ portable machines is typically only several weeks.
In other words, the increase in efficiency and labor savings that this equipment delivers
usually pays for its price on your first project.
Because of their additional efficiency, Mr. Lackner recommends our air-assisted hydraulic
models for anyone who will use them for just one medium size project or for repeated
small projects.
You can reach Ray Lackner personally at BLOCK SHEAR LLC.
While BLOCK SHEAR™
stone working and block working tools
look similar to certain other machines of the masonry trade,
the similarity is deceiving. Our machines comprise
innovative efficiency features. Patent pending.
Selecting the Optimal BLOCK SHEAR™ Equipment
Broadly, BLOCK SHEAR ™ hydraulic power splitting equipment is used to:
Split / cut masonry and pavers, or pre-cast construction materials.
Split / cut natural
stone and slabs. Models designed for this application will also
split / cut pre-cast
construction materials.
Operation & Benefits of our Stone Working Tools and Block
Working Tools
BLOCK SHEAR ™ hydraulic power-splitters come in two configurations, either as Manually-Activated or as Air-Assist-Activated. The later models can also be activated manually.
All BLOCK SHEAR ™ power-splitters are portable to the job-site. They are equipped with handcart type wheels.
Manually-Activated Hydraulic Tools
Manually-Activated BLOCK SHEAR™ tools are self-contained
and provide the highest productivity for splitting natural stone
and masonry products in the industry. At the core of this
advantage lies the BLOCK SHEAR™ designed pumping
mechanism.
When the operator places a new stone, block or slab on the
the worktable, the first time he presses the (single) foot-lever,
the worktable and the lower cutting blade move up by about 2”
[ 50 mm ] – in one move it fits the upper blade snuggly on the
blocks, stones or slabs being cut. Subsequent pumping of the
same lever drives the hydraulic actuator that quickly splits the
construction material, moving in 1/8” [ 12.5 mm ] increments.
BLOCK SHEARS™
STONE / BLOCK WORKING TOOLS are engineered to
reduce the pumping of the foot lever because the first
2'' [ 50 mm ] adjustment is only available with our unique
mechanism.
A BLOCK SHEAR™ Manually-Activated tool is recommended for
jobs that involve the splitting of a small quantity of stones,
masonry blocks, slabs or pavers at a time. For larger jobs we
recommend the BLOCK SHEAR™ Air-Assist-Activated tool.
Air-Assist-Activated
Hydraulic Tools
The Air-Assist-Activated BLOCK SHEAR™ STONE AND BLOCK
WORKING TOOLS adjusts the position of the worktable and
splitting / cutting blades and makes the cut even faster.
The operator simply squeezes the air trigger - the adjustment of
the table and blades, and the cut follow. Our Air-Assist-Activated machine requires only a small outside compressor. A portable one
is perfectly adequate. Furthermore, compressors are usually
available on job sites.
As a back-up feature, Air-Assist-Activated BLOCK SHEAR™
STONE OR
BLOCK WORKING tools include the single foot-lever of
our Manually-Activated tools. This enables these machines to operate even when there is no compressor around.
Our Air-Assist-Activated BLOCK SHEAR™ tools are recommended
for jobs that require the splitting / cutting of a larger volume of natural stones, masonry blocks, slabs or pavers.
