String instruments and bows of the type normally used nowadays are designed for the variety of techniques normally taught by teachers of classical music. Any other techniques will result in bad sound and loss of control. To play pre-19th-century classical music or folk music of various styles, you can adapt your bowing without leaving the domain of approved technique. (Some special considerations apply to double basses, which are not the topic here.)

Before the early 1800s, instruments, bows and strings were built and handled quite differently. (All those "Strads" still in use nowadays have been thoroughly refurbished!) Some folk traditions stuck to old techniques while using newer instruments; some updated later, when they became aware of the discrepancy. If you insist on "reenacting" a particular tradition, feel free to do so, but do not expect a result closer to the spirit of the music.
