How does the reblading of Fleshing and Shaving cylinders work?

Renlaw took over the re-blading and caulking of cylinders from IMK. Operations successfully moved to our main factory in Cape Town. We are pleased that our staff were trained by the original IMK reblade technicians, who have now also retired (40 years is a long time!).

Hardy UK come to us in Cape Town for training and negotiations to ensure the best product and process for all. Renlaw is the preferred supplier of Hardy shaving blades in Africa.

While it is no secret that the blades themselves are imported from the UK, this is not a game just any blade manufacturer can step into.

The reblade process requires technical precision and an integral understanding of the industries in which the cylinders are used.

Common  Industries included are leather working, tanneries and game skins processors. These cylindrical blades need the strength to do their job, but not cause any damage to the valuablee skin or leather.


Replacing Fleshing and Shaving blades:

When the shaving cylinder arrives at the factory we perform a thorough inspection to ensure that there are no abnormalities in your cylinder.

The cylinder is secured so that the worn blades can be removed safely. We carefully take the spiral up and out of the groove in a continuous spiral motion. This is how we lift the blade without damaging the groove walls. Once the blade is removed from the groove, the caulking is extracted using purpose-built grips.

Next we prepare the cylinder to fit the new blades. It must be thoroughly inspected and cleaned.

We proudly use Hardy blades that we import from the UK. Hardy shaving and fleshing blades are engineered so that the portion fitted into the cylinder groove is slightly ‘softer’ than the rest of the blade to allow for a safe re-blade process without compromising on performance.

Blades which are too hard at the setting edge have a tendency to fracture. Renlaw’s Hardy blades are tough and pliable at the core and rock hard and sharp on the cutting edge.

The new spiral blade is now fitted.

We use copper caulking to secure the blades. Copper holds the blade best and causes no damage to the cylinder during the removal of old blades and fitting of new blades to your fleshing cylinder.
