High carbon steel

High Carbon Steel Brick jointers can be forged from a single piece of carbon steel for added strength. High carbon steel contains approximately 0.8 – 2.11% carbon content. This type of steel is preferred by many manufacturers who create metal cutting tools.
Advantages and disadvantages of high carbon steel ADVANTAGES DISADVANTAGES
  • Suitable for regular mortar finishing work
  • Very strong
  • Long-lasting as a result of its durability
  • More likely to become brittle compared to other types of steel.
  • If misused, high carbon steel may fracture
  • If used with light coloured mortar, the mortar may become discoloured

Plexiglass

Plexiglass brick jointers Plexiglass is made from acrylic plastic acid. It is half the weight of glass and impact resistant to temperatures from -34 degrees Celsius to 71 degrees C.
ADVANTAGES   DISADVANTAGES
Advantages and disadvantages of plexiglass
  • Will not discolour of leave black marks in mortar
  • Less abrasive than metal
  • May be prone to scratches
  • The smooth, curved edge may deteriorate over time
  • Difficult to clean – requires the use of non-ammonia based products

Tempered steel

Tempered steel brick jointers Tempering is the process of reheating tool steel in order to improve the metal’s toughness. This reheating is done at a low temperature range, usually from 148 to 593 degrees C.
ADVANTAGES   DISADVANTAGES
Advantages and disadvantages of tempered steel
  • Creates very smooth joints so is useful for jointing around tile and brickwork.
  • Tempering process minimises  cracking and increases workability allowing the steel to be crafted into many shapes for hand tools
  • The hardness grade of the steel is compromised as a result of the improved workability and minimised cracking

Tool steel

Tool steel brick jointers Tool steels are made under controlled conditions which make them distinctively hard and resistant to abrasion. Tool steel has a carbon content between 0.7% and 1.5%.
ADVANTAGES DISADVANTAGES
Advantages and disadvantages of tool steel
  • Used to make various tools with a heavy-duty tolerance relatively cheaply
  • Properties of tool steel vary depending on how the steel has been cooled
  • Some can very brittle, others can distort easily

Which material should you choose?

Which material should you choose? The material you should choose is dependent on how frequently you plan on carrying out brick jointing as well as the colour of the mortar you will be using.
A tool steel jointer is recommended for use with dark mortar as it is relatively cheap and hard wearing.

Tempered steel and high carbon steel increase in strength respectively and so these tools are built for more frequent use.

 A plexiglass jointer is recommended for use with light mortar as it does not leave black markings.
Wonkee Donkee says: 'Choose a heavy duty tool if you are doing a lot of jointing. This means the tool can withstand great strain or regular use.'
