In an NPC village, a villager wanted to trade me diamond axe with silk touch. If I were to trade that axe for 10 emeralds, are there any advantages over a regular diamond axe?
Looking at the page from the Minecraft Wiki, it has a few uses, which are normally unavailable to non-silk-touch axes:
- Huge Mushrooms
- Packed Ice
The bolded ones are the only blocks which you should harvest with an axe. All the other blocks in the list are better to harvest with another tool, but I put them in because it is possible to harvest with an axe.
(By the way, the axe works like a normal diamond axe, with the added ability to harvest the above items)
I have found a nice way to use the silk touch axe.
Melons when broken by any non - silk touch tool, or by hand, gives melon slices. However If you break melons by a silk touch tool it will drop melon block. So you can say no to the tedious melon crafting.
After you have a good amount of melons you can trade them for lot of emeralds.
Silk touch pickaxe is slower at breaking melons than silk touch axe So an axe with silk touch has its own unique advantages. This method of farming melons can be effective.
(P.S. melons can be harvested by silk touch tool is not mentioned in the Wiki)
There are advantages of silk touch, coal ore, diamond ore, emerald ore, grass block*, huge mushrooms, ice, lapis lazuli ore, mycelium*, podzol*, packed ice, nether quartz ore and redstone ore are only optainable in vanilla survival through a silk touched tool. Additionally ender chests, bookshelves, glass and glass panes, can be retrieved after they are placed.
(all the items with the * sign on them can be also obtained by killing an enderman holding the item in his hand)
The silk touch axe is a handy multi tool* for those with more emeralds than inventory space, along with melon, bookshelf and mushroom tree harvesting as previously mentioned.
*I use it when I want to harvest wood and silk in abandoned mines or wood and foliage (which are placed next to each other so not switching tools is nice) and don’t want to carry shears. It also has ok damage, so sometimes I forgo my sword as well, which gives me space for bow and arrows.
