I just bought a roll of Scotch 700 (7mil) electrical tape for taping the spine.
I've used this brand before with no problems, but this time the adhesive
seemed to melt and run when used with honing oil or Smith's solution.
Is there a better choice of tape, or did I just get a bad batch?
Kapton tapes come in 1, 2 and 5 mil and have non-sticky silicon adhesive.
I use supper 88 and havent had any issues when using oils. Maybe you got a bad batch as i know a lot of folks use the 700.
I'm with you. Scotch88.
Great minds think alike!
OK, maybe i just got lucky. :(
I got this huge roll from MikeB52 a long while back . I am about halfway through it.
I dunno as it is much thicker, but it is really tough. Best thing I have used.
Scotch 22
I recently started into a new roll of 3M Super 88....but turns out I really meant to get the 700. D'oh! :gaah:
I looked into 3M Kapton tape but am too cheap to spend 4-5x over what 3M vinyl electrical tape costs.
I have been using the 89¢ electrical tape from Walmart for years.
It works very well and I've never had a problem with it.

I'm with the super 88, especially the colored rolls.

Off brand kapton from ebay works well and at less than four dollars for two rolls delivered, you can't go wrong. It takes about 10 days for delivery in my case.
Kapton tape is like Crescent wrench, or Kleenex tissue. It's a brand name, not the actual object name. Polyimide tape is what you ought to be searching for, and it really isn't expensive. Also works very well. I have a whole bunch from electronics work, but I use it for honing sometimes too.
I've had the same experience. When I started honing I used some cheap tape first and then switched to 3m and thought it lasted much better. Since then I've gone back to cheap tape with no issues. Turns out that the 3m was lasting longer because my technique had improved.Quote:

It’s not the cost of the tape, if the tape has been in a hot environment, hot garage or shop, the glue starts to break down. Same tape, new, wrapped and left in a drawer or toolbox is unaffected.
I have used all kinds and brands of tape, even Harbor Freight “Cheap Tape” without issue. Except if I have left it out during a heat wave or in a car. You will see the glue ooze from the sides. Sometimes you can peel off a few turns and get to good tape, but I buy tape for $1 a roll from Habitat for Humanity so if it goes bad I grab a new roll. A squirt of WD40 on a paper towel gets the glue off a blade.
I have been using the Ebay Kapton, unless I need the thickness I use electrical. I don’t recall the price, but not expensive, it is super thin and tough.
BTW, if you use Kapton tape do yourself a favor and buy a table top tape dispenser.
Kapton is so thin it will easily fold on itself when pulled off a roll. And it can be difficult to find the end and get it started to unroll, it will make you crazy. A cheap dispenser solves all that.
I got mine at a thrift store for a few dollars. It is a 2 in wide packing tape dispenser with 2 rollers, I keep 1/2 in and ¾ inch or the millimeter equivalent on it. The tape is sold in millimeter widths. ¾ works better for razors, but you can use ½ inch.
I use ½ for honing EDC knives on an Edge Pro to protect the blade from scratches, it is easy to trim to shape with a knife.
I'm not a fan of tape dispensers unless you use the tape very frequently. They leave quite a length of tape adhesive exposed to the air. For the polyimide or "Kapton" tapes, I just fold over a little bit of the tape on itself so the two adhesive sides stick together after I'm finished using the tape to provide a little "handle" for next time. Plus I have probably 30+ rolls of tape, don't want a bunch of dispensers all over the place.
Honestly it doesn't matter as long as it's good quality electrical tape.
