Your rabbit will eventually need their nails trimmed unless they have lots of time to dig holes in your yard. Rabbits naturally wear their nails by digging hard ground but indoor rabbits don’t have this luxury.
Baby rabbits nails tend to be sharper and longer cause their quick (vein inside nail) is super long and you can normally only take the tips off. Bandit only gets a milimeter or so removed and he’s 4.5 months old. This is just to remove super sharp points but his nails are not long at all.
When you should worry is if you can see the nails past the fur line and your bunny looks like wolverine starting to extend his pokey blades. For me I took my baby to the vet to get his nails trimmed first and they performed it. The next time I was holding him and my local shelter did it, and this time I’m going to do it by myself.
Your bunny might also not be used to you touching his paws, I countered this by giving him a few pets and when he relaxed and loafed I stroked his paws for as long as he would allow. It took time but now I can touch his front paws at will but he’s still sensitive about his hocks. In the habitat board here I also made a post about a fix box I made for him and he loves to dig around inside it this removes sharp points and dulls them down a bit. As for other surfaces you can get your bunny a seagrass mat to dig on as well as they are bunny safe if they have no rubber backing
