Unless you've tampered with or tempered them, they shouldn't break.
For around $20 and a few $$ S/H ... you can get Grousefly to custom make you 100 jigheads. Head weight/hook size/hook color of your choice.

Click on the "images" link (right hand side of page) ... then click on the pics of his jigheads, for a closer view. These are not all that he makes !!
I use his jigheads, and I've never had a hook "break". But, don't take my word for it ... ask DonG what he thinks of them ;)
