didn't wolverine fight 5 greatest samurai masters in all japan's history in an after life Japanese myth dimension?
1. besides that he was trained by Ogun himself in the way of the "samurai" he even beat him silly with his bokkan sword when he lost his temper..
2. he has fought shingen in three duals 1st time he was poisoned, beaten near death before he faced him. although logan lost the 1st match he lasted a while in such a state. In the rematch healthy he killed shingen he took some damage but he traded a stab for a chance for a kill blow... 3rd time shingen was revived and logan ran through him stealing his sword and killing him without even noticing him.
3. he has fought lazear various times in dual matches with his claws or knifes and won repeatedly... he even fought lazear and the woman who stole his soul at the same time w/shogun present. he straight out unarmed lazear and took them down b4 making a deal for his soul.
4. he fights deadpool repeatedly in a sword to claw fight.. his claws may not be a sword but they are bladed wpns showing his response time and even fight skills...
5. he practices sword fighting off and on, on his own time. he retrained with an old woman in blind sword fighting b/c he felt he needed to retrain and hone his skills again. logan seeking training from ppl whether its from an old woman or silver samurai isnt a sign that he isnt as skilled or is not capable of fighting as well in sword fighting. he may need to regain his confidence and refresh his skills but by no means does it mean he isnt as skilled or superior as some one as taskmaster or Silver Samurai.
6. logan went on a inter-dimensional rescue mission while working for LL&L and used a bokkan sword to fight his way through and refused to kill... he was using decapitating techniques nerve and pressure points to defeat various superhuman beings. prior to that adventure he was living in the mountains training while on sabbatical in sword fighting under another sword master.
7. fighting Silver samurai on a regular basis
also i am sure he trained kitty in sword fighting and certain female x men...
i thing his knowledge ans skills seriously outclass taskmaster even if ppl just want to look at the comment he made to SS about needing to be retrained which i look at as just getting back into practice... nothing none of us havent done in some way in our life's when it comes to a hobby or skill......
