I recommend Beserk but it's a male lead.
If you want a strong female lead, I suggest:

For anime, probably Ghost in The Shell. Violet Evergarden is nice but nowhere near the tone of Claymore lol. Kino no Tabi is good too (2003). Maybe Black Lagoon?
Not a manga but a novel. Lady is reincarnated into an otome game but the setting and romance are nowhere near the character. Instead, there's a lot of political power plays, conflict on the foreign borders, military training etc.

I should've said besides berserk because I'm a huge fan of it
well if you're interested, you can always make a female lead in dark souls or bloodborne and live out that dark fantasy U: 10/10 amazing experience inspired by berserk
Does anyone know of any shows or manga like claymore?
I've been a big fan but I can't seem to come across shows like it
When I try to look up some strong female lead manga here on mangago I usually come across some uninteresting shoujo which kind of become a pain
