 Edge Cordless Hotknife

The Sailrite Edge Cordless Hotknife is designed to separate and cut 

lengths of rope, webbing, bands or synthetic fabrics and cords.
 Do not 

use on natural fibers like cotton or hemp. The hot cutting blade cuts 

quickly and precisely and provides a clean, sealed edge. Always use with 

an insular cutting surface like the Tempered Cutting Glass for Hotknife 

(#121915, sold separately) or the included cutting foot.

Operation & Use
1.  Loosen the top and bottom locking screws (while hotknife is cold). 

2.  Insert both legs of the cutting blade. Spread or squeeze the posts 

slightly as required. (The fit may be tight.) 
Push in fully and tighten 

both screws.

3.  Attach the battery pack into the hotknife body by sliding the lithium-

ion battery pack into the base of the tool body so that the gray 

release lever is facing the cutting blade and an audible click can be 

heard. This means the battery pack is secure.

4.  Hold the spring-loaded safety button while toggling the trigger On/Off 

to control the rate of cutting and to cycle the tool power. The cutting 

blade does not need to be red hot at all times to cut through the 

desired material.

5.  Release the button and allow the cutting blade to cool down after use 

and before changing it or putting the tool back in its case. 


6.  Clean the cutting blade with the enclosed wire brush once blade has 

cooled down.

7.  Remove the battery prior to storage. To remove the battery, press 

down on the gray release lever located on the lithium-ion battery 

pack and slide the battery out.

Inserting the Cutting Foot (Optional)
1.  When the cutting blade is cool, loosen the bottom blade lock screw 

using the hex key and insert the slotted end of the cutting foot 

beneath the cutting blade. Position the foot so the blade is centered 

halfway down into the opening, creating a scissorlike shape between 

the cutting blade and the top of the foot. The cutting blade should not 

touch the cutting foot on any side. The cutting blade can be gently 

bent to fit more centered within the cutting foot. 


2.  Insert the side locking screws (included with the cutting foot) and 

then tighten all locking screws to hold the blade and foot in place 

using the hex key. Improper blade installation will prevent the 

hotknife from heating up.

Charging the Battery
This lithium-ion battery can be charged at any time and will not develop 

a “memory effect” if it is recharged after partial battery use. Remove the 

battery pack from the Edge Cordless Hotknife when the blade is cool.

To Charge the Battery
1.  Connect the rechargeable battery to the supplied charger by sliding 

the top of the lithium-ion battery pack into the prongs on the top 

of the charger, so that the gray release lever is facing down (See 

drawing below).
 Then plug the charger cord into an outlet. 

2.  There are two indicator lights on the front of the charger. When the 

battery pack is securely attached to the charger, the light will turn 

red. When the battery pack is fully charged, the light will turn green. 

3.  There are four indicator lights on each lithium-ion battery pack 

that light up to indicate the battery charge level when the button 

is pressed.

4.  The indicator lights will taper down as the battery loses power while 

you use the hotknife. So, 4 green indicator lights mean the battery 

is fully charged and 1 indicator light means the power is very low.

5.  An empty battery typically needs approximately 90 minutes for a 

100% charge.
