If you liked the Claymore manga, the Anime-Planet community thinks you'd like:
Köinzell is a master swordsman who, along with thirteen other heroes, was sent by the Szaalenden Empire to block an invasion of their enemy Wischtech. Along the way three died, four betrayed the others and seven defeated the traitors and returned as heroes. At least, that's what people believe. In reality the ‘Seven Heroes' were the real traitors, defeating the four true champions after the seven had fled the battle in cowardice. Köinzell has bided his time for twenty years, honing his skills and recovering from the brink of death so that he may avenge his fallen comrades. The time for vengeance has finally come and all who stand in his way shall be dismembered without hesitation, but it won't be easy as everyone believes the lies of the traitors. With all the soldiers in the land and the public against them, Köinzell and his ragtag allies may have to sacrifice everything if they are to prevail against the might of the entire nation.
Medvial times, swords fights, fantasy creasures such as elfs and demons and an amazing story. Both of these share those same treats, if you like one you'll definetly enjoy the other.
Both Claymore and Ubel Blatt are medievalish, fantasy, action adventure series. Both of those are rather dark and contain lots of gore (keep in mind that Uble Blatt contains more mature themes than just that). If you liked one of those two, then checking out the other one might be worth it.
Ichigo Kurosaki is an average high school boy with a not-so-average ability to see spirits - something that hadn't affected his life much until a strange woman entered his room one day. Named Kuchiki Rukia, she's a shinigami who was sent from the spirit world to destroy a hollow - a dead-soul-turned-monster; and much to her surprise, Ichigo can see her. When the hollow suddenly attacks his family, Rukia intervenes and is injured in the process, leaving Ichigo to fight it himself. But when Rukia lends him her shinigami powers - which is forbidden - he inadvertently drains them away and has no way to return them. Now, Ichigo is a full-fledged shinigami who must juggle his studies with his newfound duty of fighting hollows; but having gained his powers through forbidden means, the spirit world isn't going to leave Ichigo alone. Ichigo and Rukia must keep their situation a secret from the other shinigami, or the consequences could be dire.
Fighting, that's what brings these two together: Fights that span most of a chapter, spilling out into others and filling up a volume with violence of a badass degree. While Bleach contains a healthy dose of fancy lad's magic and Claymore on the other hand is devoid of magic overall, both still contain the roots of good, quality sword fighting, be it magic swords or just big-ass blades.
Claymore is also the more serious of the two, firmly maintaining drama over comedy but Bleach tosses it's chips in to match it with the twists and turns of it's plot and serious moments to raise the tension. Guess it doesn't help that both worlds are a world of badass on their own, where generally non-humans combat otherworldly creatures. There are exceptions but the fantasy/supernatural reign supreme.
The series Blood + and Claymore involve strong female leads that are aloof and cold up front but display tender moments in them. Each takes part in slaying the demons of the world but also have to look within themselves to control their own demons. Both have a fantasy like quality to them.
Claymore and Blood the Last Vampire each revolve around demons. The series are dark and twisted following the struggles of the main characters as they are exiled from the people around them.
