Hello! I have created a detailed guide on Tool Crafting combinations for Hammerting!
There were similar resources but I hadn't seen anyone break everything down in full detail, and I prefer to have full accurate information for everything craftable in the game. I organized and color coded the most useful information in one concise cheat-sheet, designed to be easy to reference quickly and effectively. I hope you enjoy this quick guide and it helps you save time in deciding not just what may be the best weapon, but every available alternative for when you don't just have the "best material" for everything.

Made to view well with "Dark Reader" for Chrome and Firefox, but fine without as well.

Scroll to the right for per-tool breakdowns of what the best parts are!
Detailed explanation below. Thanks for checking it out!

Last Updated: Aug 29th, 2021 : Stable Branch 0.9.20

: Includes the Following :

: [Section 1] All material resource values detailed and color coded by quality (Hardness, Preciousness, Resilience, Weight, Level).
: [Section 1] Weapon and Tool components and their specific multipliers.
: [Section 2] A quick cheat-sheet of which stats are positive and negative for each job type.
: [Section 3] The bonuses each tool blueprint offers.

: [Section 4] Detailed tool breakdown with each component made with every possible material, calculated to a total score that it would give for the applied job.
:: [Section 4] Sorted by Job Type, then by Blueprint and applicable heads and handles. Color coded to rank the performance of each combination.
:: [Section 4] Includes all tools and weapons as of 0.9.20.

: [Section 5] Detailed armor and clothing breakdown showing what all component combinations offer for each stat on the armor.
:: [Section 5] Extra cheat-sheets of best armor component combinations for different goals, and the final stats for the combination.
:: [Section 5] Certain stats on the armor and clothing currently do not increase as they should, notes provided to clarify.
:: Includes all armors as of 0.9.20.

: Rarity is not in calculation but currently it is only a small flat bonus of +20/+30/+50/+80 added before the job bonus is applied. This benefits poor performing tools the most and high performing tools the least. I have requested the devs to change this to a percentage bonus.

: To-Do :
::: Factor in blueprint bonuses/penalties to Preciousness and Weight in final calculations. Done!
::: Add Armors. Done!
::: Add both hammer heads to blacksmith, metallurgy, building and whitesmithing. Done!
::: Add Jewelry. (Currently I don't think there is much difference in Jewelry, optimal is likely just orichalcum, preciousness. The most important factor in jewelry bonuses is actually rarity, unlike in tools. Mythic far outclasses the rest, even if made of copper.)
::: Add axes to sheet. (Currently left out because they do not perform best in slot for any job. But I do find they are useful to craft in bulk to sell to factions requiring axes with double (!!) or triple (!!!) demand. Orichalcum [hawk head, curved handle] works well for this if you have a lot.)
::: Calculate speed bonus on weapons, supposedly Burnished Demon Bone Handle outclasses everything due to preciousness adding speed. (Not sure how to definitively calculate the speed effect on combat at this time.)

Sections are divided from left to right.
: First section: Material and component lists.
: Second section: Job efficiency guide.
: Third section: Blueprint job efficiencies and bonuses.
: Fourth section: Full combination breakdown for each item by job.
:: Scroll to desired job type; i.e. Blacksmithing.
:: All relevant components are listed with the best scoring tool head and handle highlighted yellow. Close alternatives in green.
: Fifth section: Full combination breakdown for all armor and clothing.
