you can't.blaze rods are only obtained after killing a blaze.
Blaze Rods are an item drop you get from defeating Blazes in the Nether.
You have to go in the Nether and find a nether fortress, the Blaze mob is the one that drops blaze rods. They can spawn in the fortress without a spawner but they are very common when you are near one. You can make a roof over the blaze spawner so they are trapped because the way they move around is flying and hovering. Its better to kill a blaze using that method with a sword than it is to use a bow on a blaze out in the open. Blaze rods can be used to make Brewing Stands and Blaze Powder.
You don't make them, you have to find a mob called a Blaze in the Nether (almost always in Nether Fortresses), then kill them to get Blaze Rods, which they may drop.
It can be used to make a Brewing Stand, to brew Potions. Also, it can be crafted into Blaze Powder. They can also be used as fuel in a furnace.
Before anybody reads this, I want you to realize that you need to think about Blaze Rods before turning them into powder. Blaze Rods are essentially a stick with Fire Aspect and they are essential for defending yourself from things that go bump in the night. The rods can also be used as fuel in a furnace, being more efficient than coal. They also make you a brewing stand. Now, back to your answer. Blaze Powder can make: Magma Cream (a shapeless recipe, just place a slimeball and a blaze powder in the grid) Eyes of Ender (also shapeless, using an Ender pearl (endermen incoming) and a Blaze Powder) and Fire Charges (ALSO shapeless, using Blaze powder, coal or charcoal, and gunpowder) Hope I told you about the usefulness of Blazes!
You don't craft Blaze Rods, they are an item drop from killing Blazes in the Nether.
There's a monster called a Blaze, they spawn in the Nether, in Nether Fortresses. Blaze Rods are their drop item.and Blazes you can find them in the Nether.and there spawn er. there from the fortress of it and when you put water you can kill it ,because its weakness is water.

Carp rods are much more stiff and have a thicker blank compared to a normal rod. This is due to the fact that carp rods are specifically used to catch bigger fish. Also, carp rods have much bigger rings and are much more solid.
