Textures appears blurry on the objects I make!

Hi everyone! I model my own 3D models on Blender then export them as FBX files to Unity. The object is working fine, but when I apply a texture from Unity, then it becomes completely blurry. The texutres works fine with any other object in general. I am new at modelling so I do not really know how to increase polygon etc.

I did make a little research but could'nt find anythign, so I wanted to come here and ask!

Here is a picture of my object compared to a arm model: http://gyazo.com/e19253539f1cb143f1e163103291b4f9 Both uses the same texture, but my axe is blurry.

Please help! :)
