If you say the marker is being removed from the heal then keep honing untill it feels sticky sharp with the tpt. whatch heavy dutys honing video on the warped blade section i think 9 and watch him hone very carefully all the way throught the progression and you will notice he starts with the heal down first on his normal blade study his honing and try and practice i learn't alot from his viceos every thing his in there. go to video section i think hes on there or utube on hoining straight razor he also uses bbw and yellow you must watch all the way through i have watched at least 10 times.He explains why he puts heal down first as in his experiance the heal does'nt spend much time on hone and he had a thew razors that wern't getting sharp at heal so that is why he hones that way i do now and i find it works realy well with good consistant strokes and normal light pressure always.
