How to use a small single lever action sprue cutter

 
 A small single lever action sprue cutter should be held in one hand with one of the handles resting in your palm and the other on the pads of your fingers. 

Step 1 - Hold cutters

This type of sprue cutter should be held in your dominant hand. One of the handles should rest in the palm of your hand, while the other should rest on the pads of your fingers.

 
     
 The flat outside edge of the sprue cutter jaws should be placed up against the part being removed to achieve the best finish on the cut and minimise the filing required afterwards. 

Step 2 - Position cutters

In order to achieve the best finish on the cut of a sprue, you should place the flat outside face of the jaws against the edge of the part you are removing. This will help to minimise the size of the nub left on the part being removed from the sprue.

 
     
 To reduce the effort required to cut a sprue the sprue should be placed in the recommended cutting area of the sprue cutter jaws which is between half way along the cutting edge of the jaws back to the joint. 

Make sure the sprue is in the recommended cutting area of the jaws. This will allow you to apply the greatest cutting force possible with the sprue cutter and minimise the effort required.

 
     
 Squeeze the two handles of the sprue cutter together between your palm and fingers to close the jaws together and cut a sprue. 

Step 3 - Cut sprue

Bring the jaws together by squeezing the two handles between the palm of your hand and fingers. 

 
     
   

How to use a large compound lever action sprue cutter

 
 Unlike smaller sprue cutters large compound lever action sprue cutters are held with two hands. 

Larger compound lever action sprue cutters differ in their operation from other sprue cutters mainly because you use two hands to operate them. 

 
     
 Holding large sprue cutters with each hand at the base of their handles will allow you to apply more leverage and cutting force. 

Step 1 - Hold cutters

You should hold large compound lever action sprue cutters with one hand at the base of each handle. This will allow you to apply more leverage and so a greater cutting force.

 
     
 To reduce the effort required to cut a sprue the sprue should be placed in the recommended cutting area of the sprue cutter jaws which is between half way along the cutting edge of the jaws back to the joint. 

Step 2 - Position cutters

Place the wire or sprue between the sprue cutter jaws within the recommended cutting area. This is particularly important with thick or hard materials in order to reduce the effort required to cut them.

 
     
   

Step 3 - Cut material

Press the handles together so that the jaws close on the wire or sprue being cut.
