Stroft Fishing Lines

What is the STROFT philosophy?

The aim is to offer the world’s best fishing lines under the utilization of the most modern technology available. See also: WAKU; the company history this far. In order to reach this goal we focus solely on fishing lines, concentrating all our energy and capacity in this produce – we’ve been doing this for over 35 years. Through constant contact to leading departments that concern themselves with the research and development of plastics and monofilament technology, and through our own tireless tests and experiments we have developed a high degree of technical competence and “know-how”. STROFT fishing lines are developed “in-house” and based on our technical expertise.

The lines are then manufactured exclusively for WAKU by manufacturers that have suitable extruding and braiding facilities. Our specifications are constantly monitored and if necessary corrected. We are able to implement new developments immediately. The names of the products aren’t changed. For example, the monofilament fishing line, STROFT GTM, has experienced thirty-seven improvements. Just as the yellow fluorescent STROFT FLUOR. STROFT GTP has been improved on nineteen occasions. All this together builds the basis of the flexibility and technical superiority of STROFT products.

What does the EFTTA seal of quality mean and how is it achieved?

As a couple of years ago more and more fishing lines with unrealistic breaking strains came on the market the EFTTA (European Fishing Tackle Trade Association) reacted and set up a neutral test procedure in a laboratory in Great Britain. Since then all manufacturers have had the opportunity to have the diameter and breaking strain of their lines neutrally verified. When the manufacturer’s values corresponded with the test results then they were awarded the EFTTA seal of quality*.

The EFTTA wishes to effectively combat fraudulent manufacturers and has now created a new logo ** in order to do so. This logo** may be used by those companies that have joined the "EFTTA line charter ". By subscribing to the charter these companies commit themselves to stating the true diameter and breaking strains and to monitor and adhere to these values using appropriate quality tests. Companies giving fraudulent information may be prosecuted in court, if necessary. We welcome this new initiative, especially because we have been discussing this problem for years. The STROFT GTM was one of the first lines proved and tested by the EFTTA at the beginning of 2004 subsequently receiving the "EFTTA approved" logo. As of the beginning of 2012 you can now find the new "EFTTA logo" on all STROFT monofilament labels. More information about the EFTTA line charter can be found at Now the consumer has the opportunity to separate the wheat from the chaff. Further information on the EFTTA line test can be found here: As of now the consumer has the opportunity to separate the wheat from the chaff and buy verified quality products that carry the EFTTA label. One should certainly wonder why some products do not carry the EFTTA label, particularly when the breaking strains seem comparatively high.

Monofilament Fishing Lines
The US magazine „Fly Fisherman“  published in May 2012 the so far probably largest test of monofilament fishing lines with 30 different products. The tester measured the average breaking strength (without knot) of all products in relation to the actual diameters.  Afterwards the best products have been undergone a knot test with 22 (!!!) different knots.
The overall  “Breaking Strength Winner” of all  tested brands is STROFT GTM.  Read the test.

The fishing magazine „Rute und Rolle“ published the results of a test that had been carried out by the TUV Munich (German standards organisation); various properties and characteristics of 10 monofilament fishing lines from a range of manufacturers were compared. E.g. the stated thickness - actual diameter – knot-strength before and after stretching the line - the elasticity before and after having stretched the line - the knot-strength after being stored in a hot atmosphere - the elasticity after having been stored in a hot atmosphere. The unquestionable winner was STROFT GTM. Read the test.
