Insights in Rope Quality

by | Oct 31, 2018 | Blog, Rope Data

When I decided to buy my first set of ropes, I searched the internet, magazines, forums for any qualification that could tell me what kind of rope I’m holding; insights in rope quality. Since the rope for bondage was never intended to tie human bodies, it must have been coming in different qualities, grades and strengths for different industrial uses. But no clear answers to be found. Moving up from a local Fetish-store, to several retailers in the UK, US, Italy and Japan, I found that there was so much diversity – a taste for every fetisj -and at the same time so much troublesome qualities, additives and risks, I needed to know a lot more about this, eventually leading to the decision that should excel in retailing the highest grades, cleanest qualities and sustainability as a key-driver for putting together our product-range.

Over well a year ago I met a great individual, eroticist, ropist and engineer, who new more about rope than many other self-acclaimed experts could tell me at the time. While collaborating with him in the last year on rope sales, business design and eventually crowd funding our Premium Tossa (1st grade – which is soon available). For all those that love to know more about the beautiful piece of natural power in your hands; here is the standard we are using.

We intend to share a lot more of our knowledge in the coming months, so stay tuned for more insights into rope for bondage.

Rope quality

Fibre grade is imperative. The higher the grade, the longer and stronger the fibres. Filament length, torsional rigidity, fineness, uniformity, cross sectional shape and lack of imperfections are all critical factors for rope strength. Any imperfection is a weak point.

Bangladesh and India use different systems, e.g. BTS (Bangla Tossa Special), BTA, etc. are only paper trading grades. With the advice of the mill, we aggregate grading thus:

  • Grade 1: uniform golden to reddish of the finest structure, min. filament 1.5m very strong and very good lustre, completely free of defects and blemishes, no breaks, dark bark, waste, specks, cuttings or habijabi tangles.
  • Grade 2: uniform silver grey to golden of fine structure, min. filament 1.25m, strong and good lustre, completely free of blemishes.
  • Grade 3: clean, sound, light/medium grey to copperish grey of good texture, fairly strong and good average lustre, min. filament 1m, free of blemishes.
  • Grade 4: mixed colours, fair to average strength, occasional bark and soft specks, but free from runners, min. filament length 0.75m, slightly cropped and gummy tops permissible, free of black wiry tops and root ends.
  • Grade 5: average colour and strength, min. filament unspecified, occasional bark and speck, croppy and gummy tops permissible, but free of black root ends and runners.


Quality is strength. Analyse and grade your own rope. Take a length and unwind the strands and yarns. You may find complete yarn breaks, dark bark, waste, specks, cuttings and habijabi tangles:
