This list is in no particular order though only should show the quality of Rabbis that are proudly wearing Tekhelet from the murex trunculus. The intent here is so that one can see these Rabbis and know that there’s justification in wearing these blue strings despite what detractors might say. The following list is mostly courtesy of “Mi Yodeya: by Hacham Gabriel.” The comments and research are mine.
The Generic/Black Hat Crowd (12)
R’ Yisroel Belsky ZT”L
R’ Belsky ZT”L had a complicated relationship with Tekhelet. He likely was influenced by R’ Schachter while working together for the OU. He wore it on his regular Tzitzis when wearing a long frock coat to cover it, as well on his Shabbos Tallis. He didn’t like talking about it much and didn’t wear it on his weekday Tallis. My guess is he didn’t want to face negative backlash from the Haredi community and his affiliation with Torah Vodaas which has gone in “that direction.” This is nothing new: my father told me personally that in his time at Torah Vodaas in the mid-late 1970’s when people were starting to research it, the general attitude was that “this is nonsense.” R’ Yisroel Reisman, who is presently one of the Roshei Yeshiva at Torah Vodaas, has been vocal against it, saying there’s a “zero percent chance” that the murex is the techeiles source (which has been addressed by R’ Aryeh Leibowitz since that lecture). R’ Belsky also told his kids that they don’t need to wear it, and they don’t. Ask any Torah Vodaas alumnus in the last 10-15 years for confirmation on the above.
“ראיתי בירחון אור תורה (תשע”א אדר ב’) בענין התכלת מה שכתב הרב מרן ראש הישיבה שליט”א שנוהג לשים רק בשבת תכלת.
1. למה אם שם זאת רק פעם בשבוע זה לא נחשב כמוציא לעז על הראשונים?
2. ועוד כתב הרב בשם הרב אלישיב שאין לחייב את העם בתכלת, מה כוונת הדברים?
3. והאם ידוע לרב אם הרב אלישיב היה בעצמו שם תכלת בציצית?
4. ומתי יהיה נכון לחייב/להורות לרבים לשים תכלת?
הרב המשיב: הרב יהונתן מאזוז שליט”א
1. כשהרב שם רק בשבת הדבר מוכיח שזו הנהגה חדשה שלא נהגו בה אבותינו, ולכן בשאר השבוע אינו שם, ובשבת שם כעין חומרא.
2. הכוונה היא, שאין לנו מסורות ברורות שזה זה ודאי התכלת של מצוה, אלא ראיות שבזה היו משתמשים בעבר לצביעה והסימנים בש”ס מתאימים לזה. וזה לא מספיק כדי להורות לרבים לחייב לשים תכלת, בפרט שאינה מעכבת בציצית.
3. שמעתי שהביאו לו טלית קטן מצוייצת בתכלת והרב זצ”ל לבש כמה רגעים והוריד.
4. כשיבוא המשיח.”
א). האם ראש הישיבה שליט”א סובר שהתכלת הידוע כיום זה הכלת האמיתי? ואם כן מה שמו של הדג האמיתי, המדעי שממנו מפיקים את התכלת, ומהיכן מוצאו של דג זה? ב). מי מפיק זאת? והיכן ניתן לרכוש חוטי תכלת אלו? ג). כזכור לי שראש הישיבה אמר שבברכת: “לישב בסוכה” הניקוד שבאות ‘ב’ זה עם פתח והאות מודגשת וזאת מפני שזו הסוכה האמיתית שצריך לישב בה בכדי לצאת לידי חובת ישיבה בסוכה. ומאידך על ברכת: “להתעטף בציצית” האות ‘ב’ היא עם שווא וההסבר שפשוט היות ואין אנו יודעים מהו הדג האמיתי שממנו מפיקים את התכלת לכן זה עם שווא ועד שיתגלה יהיה עם פתח. האם נאמר שכיום עם ההוכחות האות ‘ב’ תשתנה לפתח כמו בסוכה שזה התכלת האמיתי? ******* נשמח למקורות ומה גם שמענו שראש הישיבה שליט”א הוציא קונטרס על כך, האם ניתן לקבלו לכולל שלנו.
הרב המשיב: הרב יהונתן מאזוז שליט”א
1. עיין בעלון בית נאמן (מספר 17 פרשת בשלח שיעור שנאמר בפרשת בהעלותך)
2. אגודת פתיל תכלת של הרב טבגר ונמכר בחנויות טליתניה ועוד.

Rav Eliyahu Tavger
R’ Tavger was the first person to wear Tekhelet with a Bracha.
“Rav Tavger is the Rabbinical advisor of the Ptil Tekhelet Association. His involvement with tekhelet began in his kollel studies during which time he published his first work on tekhelet in the Journal Moria, with the blessing of HaRav Hagaon Shmuel Auerbach S”hlita. Further in depth research of the subject led to the publication of his seminal work “Klil Tekhelet”. In 1988, his research culminated in the first ever dyeing of tekhelet for the mitzvah of tzitzit from the Murex trunculus since its disappearance 1300 years prior. Rav Tavger then joined the founders of Ptil Tekhelet to become the organization’s guiding light.
