I use rope and knots for pretty much everything, and though the whole tape + cut + lighter method works okay, the resulting cuts can be inconsistent and require 'tiding up.' Not wanting to pay for a dedicated unit to cut rope, I picked this up to use in my older Craftsman 1,500 watt soldering gun and honestly I can't see myself ever going back to the old way of cutting rope unless I'm in the field.I've read some reviews where people say it works great but it's difficult to hold the rope and press the trigger on the soldering gun to make even cuts and that is true. I've found that, for me, the best method to use this is by wrapping the trigger with rubber band or something similar to keep it depressed, then plugging the soldering gun into a momentary trigger foot switch. Then I can just press the foot switch each time I need to cut the rope, allowing the use of both my hands.

I purchased this tip for 3 reasons:1) I need to cut nylon and polypropylene rope2) I already owned a Weller soldering gun, and3) I really wanted a nice rope cutting tool like this:, but couldn't possibly justify the price for my needs.Once I got it, I found that it does exactly what you think it does: it cuts rope, and does so relatively well. Once it's hot, it cuts through both nylon and polypropylene rope, even fairly heavy rope, with relative ease - and nicely melts both ends to seal and prevent fraying/unraveling of the rope.Besides that it does what it's supposed to do, another positive is that it's much safer than using a match, lighter, candle, or torch to melt and seal the ends of the rope. Nobody really enjoys having hot liquid nylon drip onto their bare skin!There are a few things that you should be aware of:1) It takes a little while (perhaps 45-60 seconds) for the tip to heat up to good working temperature from a cold start. I am sometimes impatient, and forget this... but if I prepare my work correctly, I'll get the tip hot and do several cuts consecutively while holding the gun trigger to keep it hot.2) Over time, I have found that it tends to collect burnt rope residue. This was a minor annoyance at best, however - it takes just a few seconds to scrape the hot blade with a flat-bladed screwdriver to clean it for further use.3) It requires some degree of coordination to hold a rope to be cut with one hand, and the soldering gun with this tip in the other hand, and to make good clean cuts. But if I was able to do it, most people should also be successful. Some people may find better success laying the rope to be cut on a piece of scrap wood, so they can cut through with this tip and risk only heat marks on the scrap.If you have large volumes of rope cutting to do and/or will use the tool on a daily basis, I can strongly recommend the rope cutter I linked to above - it's great. But if you already own a soldering gun and will use it only occasionally - this could be just the tool for you. For the price, why not give it a try?It was definitely worth it for me!

This cut the nylon ropes the I use pretty darn good, but you do have to read the manual to maintain that good and fast sealing/cutting of the nylon/paracord etc. Let it cool first and use a steel brush to get the hardened plastic/nylon off.

This tip works just fine, it cuts poly line quickly and efficiently. The fitting issue noted in other reviews could be a problem for some. My Weller 8200 soldering gun is over 40 years old. For that version the ends of the tips that go into the gun have to be bent (after slipping the locking nuts over the ends). This is easy for the copper soldering tip but the rope cutting tip is steel and is pretty hard to bend. Vice grips or a vice should do the job. Once bent, the locking nuts won't come off the tip without straightening the ends and this is much harder than bending them. For the moment I have lost the soldering gun capability. Maybe newer versions have some kind of compression nut that will eliminating the bending. I put in a call to Weller to find out but never heard back.

Works perfectly on the Weller soldering gun.

Simple, nicely made item well worth it if you end up cutting synthetic lines (shoe laces, ropes, etc.) with any frequency.

Purchased to cut synthetic upholstery material with a Weller 140/100 solder gun. Works very well. I bent the straight connection sections about 45 degrees to make it a comfortable holding position while giving a good view of the cut line. It works with only a slight delay to allow the tip to heat. Unlike some hot knives it does not glow red and does not heat high enough to cause smoke and burning. This tip and gun combination is slower than Sailrite's hot knife but then it does not cause smoke/burning and require a glass or metal table top/backing to prevent burning of your table as the Sailrite does. This tip and the Weller gun combination can be used over clean chip board as a backer. In fact, if used over chipboard/cardboard as a backing the cut line will lightly stick to the backing thus temporarily securing the material in place allowing you to make very accurate cuts. If you want high speed use the very excellent Sailrite hot knife or equiv, but if high speed is not essential and you want to not smell burning plastic this tip with a Weller solder gun will get the job done.

Aunque solo ha sido utilizado unas cuantas veces, ha sido lo que se esperaba, en cuanto tenga mas uso podré saber su durabilidad.

This works on both Weller guns but it cuts slower with the 8200 Weller.So it just takes longer to cut ⅜rope

Great value rope cutter. Much cheaper to use my soldering gun than buy a whole new tool.
