I decided I'd like to try using a fountain pen for everyday writing and some sketching, and so I've bought half a dozen different ones over the last few weeks. The Lamy Safari is by far the best of the ones I've tried. I find the texture of the pen gives a much better grip than shiney metal pens, the nib writes [and draws] extremely well and has enough flex for a left-hander like me. The cartridges hold a lot of ink - though I've refilled them with Noodlers buttetproof ink using a syringe - and the pen itself looks good. I whole-heartedly recommend this pen as an excellent writing intrument.
The only pen I've found that comes even close for my particular needs of writing and sketching as a leftie is the WHSmith soft touch cartridge pen [half price offer at £] but the Lamy is the best option. Definately worth a tenner, and I'll be ordering the fine nib wersion too.
