I love fountain pens. My handwriting is way better with FP than using ball point pen. I started with camel, then pilot and then switched to Parker in my school days. After almost 8 year break I decided to get back to FP last year and bought Lamy fine charcoal pen after reading some recommendations. I didn't like it and after writing 4 pages my fingers started hurting. Is there a decent FP that anyone here can recommend ?
