Takeaways and Where to Buy
The KACO Edge has impressed me so far, and I’ve also had positive experiences with my KACO Sky and KACO Retro fountain pens. Look for additional reviews to follow. You certainly can’t argue with the price point of any of these pens (generally the sub-$20 category), which punch well above their weight in terms of design, components, and overall writing experience. I would grade the KACO Edge as the best of the bunch, due to the materials used, manufacturing quality, and the fact that the pen sports a reliable Schmidt nib.
As noted, you can easily acquire the KACO Edge via Amazon, which is how I purchased the pen pictured here. Most KACO products are Prime-eligible (at least as of the time of this review), meaning that they will be in your hands a couple of days after placing your order, if not the same day. Note that the KACO Edge does not ship with a converter in the box, so if you’re interested in using bottled ink with this pen, you will need to purchase a Schmidt converter separately, or you can sometimes find sellers who will throw in a KACO-branded converter.
Follow-Up and Editor’s Note
Despite the overall good quality of both Wing Sung and KACO pens, I've experienced cap cracks with both, which I accept as par for the course in this price bracket. At sub-$20, you're going to have to accept a lower level of manufacturing quality control on the front end, and what becomes important is the extent to which the retailers and manufacturers will support their customers on the back end. In the case of the KACO Edge, I was warned by a reader to be on the lookout for cap cracks, and a week or so after finalizing my review, I found one. I reached out to the Amazon Seller (who I assume is affiliated with KACO), who literally responded within 5 minutes offering to mail me a new cap, and requesting that I send her a photo of the crack with details of its location so she could share with the factory. I was quite happy with this level of service!
