nib overall shape improved through personal research #1 --> not enough bending amount, thought to be an effect of "spring-back" phenomenon. #2 --> V-bending phenomenon @ skyblue dot, thought to be inevitable. so far, #1, 2 was wrongly thought to be a consequential result of bending a springy sheet material. increasing press pressure by 10x improved overall shape. especially, improving #1 was vital, because when the nib is slitted, a deformation oc.. 2020. 12. 23.
glossy finish done for both urushi & nib (from previous post) not being satisfied with the finish, i applied the final polishing for urushi. (same pen from previous post) also the high glossy finish of urushi caused mismatch between urushi and nib. therefore, i also gloss polished the nib. now, it's complete.... harmony 2020. 12. 20.
raden tamenuri challenge started! this is my first time dealing with raden tamenuri urushi technique. this is deemed to be one of the most challenging urushi works. for the shells, I decided to use smaller particles, instead of larger ones. i believe this has many advantages over larger particles. even the tiniest shell particles will be used, to provide "mechanical interlocking properties" for urushi. like concrete, cement alon.. 2020. 12. 15.
raden urushi (na-jeon) technique research raden urushi will be done within this week, research is current ongoing, to achieve a mass produceable, consistent & durable, raden urushi technique. test will be done within this week, and if things go well, its process will be applied to all currently made pieces. that includes custom b&c, as well as fountain pens. various colors of sea shells will be applied something like this, below is just.. 2020. 12. 14.

edson & visconti nib retipping (part 1) i've received two exotic nibs. one is 18K edson, the other is visconti palladium 23K both nibs are in bad condition. edson barely has a tip, visconti doesn't have any. visconti palladium 23K may be a challenge, as it is very exotic material. this is before the repair state: edson: visconti aside from the exotic shape of edson, welding was straight forward. palladium 23K required much more energy.. 2020. 12. 1.
MontBlanc 146 Retipping the pen owner Kang (from S.Korea), sent me this pen. as matter of fact, this is the second time i received it. first time was a year ago, and i was not confident enough to retip the nib. however, a lot has happened since then, and I have obtained higher skills regarding nib fabrication. after a year or so, i had much more proficiency in following categories: -welding -slitting -nib smoothing / p.. 2020. 11. 16.

urushi technique V5.0 (soon to be developed) Good news everyone! Currently urushi technique V5.0 is being developed. all current reservations and future ebonites will be finished with this technique. for the current reservations coated with V4.0 urushi technique, the urushi layer will be stripped to the base material, and they will receive newer surface treatment that will pefectly absorb the urushi from V5.0 urushi technique.

Walnut/Hardmaple urushi Cross pen rest upgraded. thanks to R&D, Mass production is soon to be started. A Major speed & quality improvement in the sanding process, as well as urushi coating process will enable much higher yield production. the price will be much lowered as well. the below photos show the urushi coating (1st layer, black urushi) more urushi will be applied the close most of the pores, followed by a final original urushi color. 2020. 8. 14.
Faceted B & C Machining Process Has been Upgraded Compared to previous process, the end portion is cleanly cut, without vibration. Also, Various angles are now possible. in addition "Screw" style can also be done, and will be created in the future. the biggest improvement is the production speed. now custom B&C for century, gathered, duofold, etc. can also be done, as well as the symmetry models. 2020. 8. 14.

Platinum-Silver Nib, First One Made, Through Research And Study. IT's been a while since, i began using platinum material to fortify the sterling/argentium nibs. it's been quite a journey, but still not finished yet. today, i created my first platinum silver nib, an improvement from argentium silver nib. it has superior scratch resistance and tarnish resistance in terms of tarnish resistance, argentium silver did better job than sterling, but still not satisf.. 2020. 8. 4.
Dangers of working with Uncured Urushi ! Urushi is one of the strongest allergy inducing material. working with urushi always has the potential to cause this allergy. Urushi allergy will last 15~30+ days, and that's under good care. only liquid state urushi is poisonous, dried state, not so. not so sure about sanded urushi from dried state. from what i've heard, sanded urushi from dried state is almost non-poisonous, if it is very old... 2020. 7. 29.

New Silver Alloy Developed (AuAg) New silver alloy has been developed as an alternative to PtAg alloy. It is possible to make PtAg alloy based nib. however, through personal research it has been revealed, that the addition of platinum increases brittleness of the entire alloy. due to this nature, for every 10 nibs produced, half of them failed do to cracking, during manufacturing process. the rest lucky ones did not exhibit any .. 2020. 6. 16.
