The Sailrite® Edge Cordless Hotknife is the most convenient way to cut and seal lengths of synthetic fabric, rope and webbing (i.e. acrylic, nylon, polyester, etc.) that would otherwise unravel when cut with scissors. This quick-heating blade is trigger operated and can achieve a temperature of 752°F (400°C) in seconds for the fastest and most precise cuts. An internal fan regulates the tool's temperature and prevents it from overheating.

The best and most convenient feature of this hotknife is its supreme portability! It relies on an exclusive rechargeable lithium-ion battery pack for power instead of a traditional plug-in cord so you can take it anywhere you want to go. You can easily bring it with you on your boat, in your vehicle, and from work station to work station. It’s completely untethered — no more cords to slow you down! You won’t have to worry about finding an outlet or extension cord while you work. The Edge Cordless Hotknife is perfect for marine, home, automobile, outdoor and hobby projects.

The Edge Cordless Hotknife comes with two rechargeable battery packs so one can always charge while you work, and the convenient plastic carrying case provides even greater mobility. The lithium-ion batteries only take 90 minutes to fully charge. During normal usage with heat cycling (not continuous use), most projects can be completed on a single battery charge!

The charger for the lithium-ion batteries is 110-240V. Always cut on an insulated cutting surface like the Tempered Cutting Glass for Hotknife (#121915, not included) or use the included cutting foot.

Warranty: Sailrite warrants this hotknife (with exception of the blades) for a period of one (1) year starting from the date of sale. The guarantee is given against defects in material and workmanship. This warranty is voided by improper use, disassembly, repair or alteration by owner or unauthorized parties.

Please Note: This product should be used on synthetic fabrics only. Do not use this hotknife on natural fabrics such as cotton, leather or hemp. Read instructions thoroughly before use.

Was a bit intimidated before using - was worried it may mark my outdoor teak table, but it didn't! Cuts great! Easy to control and makes cutting marine sunbrella a breeze - cuts do not fray.

You’ll have to fight me first

Been in the upholstery business 25 years. I know a few things about hot knives. This is my favorite tool in the shop. If you want to take it for me, you’ll half to fight me first. :)


Good First Model

I just got mine in today. First I love the cordless freedom. It works well and does the job. The safety button is annoying, but I understand the logic behind it. It has a cheap plastic feel (should be fine as long as you don't drop it). I wish they went with a common battery system like Milwaukee or Dewalt, just for more versatility. Those things are not a deal breaker for me, but I have two big problems that I hope can be added in the second version. First PLEASE add a belt hook. And second, the holes normally found on the back of every other charger to hang the charger on the wall.


Must-Have Tool

The cordless hotknife is a great addition to any shop. It's lighter and more versatile than it's corded brother. No more plugging in at different intervals around the shop table! It's too new to rate the battery usage and charge-life, but I am fluent and familiar with a multitude of Li-ion battery tools and expect the same great results here.The only reason that I gave 4-Stars is that it's designed for right-handed users. Although it works left-handed using the side of the left index finger, the safety push-button for the trigger is inconveniently positioned for lefties and is easier to use in the right hand. Designers need to be aware and design ambidextrous tools. Lefties, rise up!!Otherwise, great tool!Allan
