Knifemaking grips are essential to perform different operations and can’t be missing in your lab.

Having a stable “block” of the knife during processing is also very important for this in addition to a quality grip also serves a stable and heavy fastening base.

The workbench must have a good structure and weight because the reminders working the metal are considerable and all unwanted movements result in little precision of the processing or force you to work with less thrust to avoid these movements.

What bit way do You use knives?

I’ll tell you essentially 4 but there are makers that create specific grips to simplify some processes that are often done.

The vice

The vice is a mechanical screw tool used to tighten and hold the parts in the works such as:

  • Thread
  • cutting/sawing,
  • Milling
  • Welding
  • mounting other elements,
  • also bonding.

The most common models used in knife making are molten steel or cast iron.

The tightening force is achieved with a hand-maneuverable screw by acting on the sliding handlebar handlebar handle.

The screw moves a movable jaw that tightens the piece against a symmetrical fixed jaw.

A key thing, however, is that you always have to interpose between the metal of the jaw of the vice and your knife soft elements such as rubber and leather at least 5 mm thick to avoid making marks on the blade that you are then forced to eliminate wasting a lot of time.

For this it is used to cover the jaws with sweet metal foils called mordacchie, usually copper, light alloy or lead, in order not to spoil the tight piece but as I told you before in kifemaking it is better to use rubber or leather.

Where the grip is used

  • At the counter the work at the vice is carried out by hand with file, sandpaper, flatbed, male, supply chain, hacksaw, drill, reaper, welder and more;
  • To the machine with the milling machine or the column drill.

 

The location

As an indication and for a person of medium stature the bench is about 80 cm high from the floor and the grip is fixed so that resting the elbow on the top of the jaws and holding the forearm vertically you can rest your chin on the hand closed with your fist.

The size of the grips is indicated by two numbers: the first specifies the width of the jaws, the second the second the width of the mouth at full opening, for example 150×220 mm. The dimensional standards of the grips are unified by THE UNI regulations 5271 and 5272, while the threading of the screw of maneuver is generally of type Acme.

Maintenance of the grip

The bits require little maintenance and when you use them you should clean them with compressed air and check that there is no chip residue on the screw.

From time to time he uses lubricated with oil or grease in particular oils the sleds and sliding parts and fattens the vine.

High-quality models have oiling points with retaining ball valves.

There are several types of grips:

  • Traditional over-the-counter bite
  • Knifemaker tube bite
  • 3D arm bite
  • The Cagne

 

Traditional over-the-counter bite

Diagram of the vice

Standard bits are the most common ones used for mechanics and are essentially three plus one I want to talk about that can come in handy for some knife work.

A) Parallel over-the-counter bite

  1. Handlebar
  2. screw head of maneuver
  3. reported jaw
  4. fixed jaw
  5. screw fastening clamp

B) Bite from tool machine

C) Morsetta

D) Two-axle bite for tools.

Knifemaker tube bite

It is a vice that allows you to move the position of the knife in different directions without having to unlock it.

Very useful when working the handle.

It is very used by American makers but not only and it is easy to build it.

This one you see in the picture is my project!

 

3D arm bite

Vice

This is a famous Red E Hand vice, very well known and is always ready to face any kind of sealing process.

Did you ever say, “Would I like to have another hand to keep it?”

Now you can!

The “red hand E” grip is a revolutionary multi-axis tool that changes the traditional design of the vice but above all the way.

It does more than just keep your project in the right place; puts your workspace right where you need it.

Perfect for any job or hobby like making knives, guns and more.

Precision processing in aeronautical aluminum;

The Red E Hand grip is built to last.

Made in the United States

Attention! There are many imitations but they do not hold like this vice that is expensive but does its job.

The Cagne

The are useful to keep the handle fixed when glued and allow the curing of the glues.

They are cheap and of different sizes.

It’s better to have a certain number!

 

Conclusions

The grip is fundamental and several are needed according to the processes.

Clearly at the beginning you use what you have but with time it is essential to equip yourself to have different according to the type of operation you have to do on the knife.

Some makers make specific bites for certain operations such as the planting of the handle in the reduced codknives.

Adapt tools to the specificity of craft or art.
